10 Crucial Email Security Best Practices for UK Businesses in 2026

Email remains the primary attack vector for UK businesses, making robust protection more critical than ever. In an environment of sophisticated phishing scams, ransomware, and business email compromise (BEC), a reactive approach is insufficient. Simply put, your email system is the digital front door to your entire organisation, and attackers are constantly trying to pick the lock. A single malicious email that bypasses your defences can lead to devastating data breaches, significant financial loss, and severe reputational damage, particularly for professional services firms where client trust is paramount.

This article provides a prioritised, practical checklist of 10 essential email security best practices tailored for small and medium-sized businesses across Dorset, Somerset, Wiltshire, and Hampshire. We move beyond generic advice to provide concrete implementation steps, configuration examples, and policy guidance to fortify your defences and ensure regulatory compliance. You will learn how to implement technical controls like DMARC and Multi-Factor Authentication (MFA), and how to address the crucial human element through effective security awareness training.

Consider this your definitive guide to securing your organisation’s most vital communication tool. Each point is designed to be actionable, helping you build a resilient security posture that protects your data, your clients, and your business. We will also highlight key areas where the expertise of a managed service provider like SES Computers can streamline implementation and provide ongoing, expert management of these critical security layers, allowing you to focus on your core operations with confidence.

1. Multi-Factor Authentication (MFA)

Multi-Factor Authentication (MFA) is one of the most effective email security best practices you can implement. It moves beyond a simple password by requiring users to provide two or more verification factors to gain access to an account. This layered defence is built on the principle of combining something you know (your password) with something you have (like a smartphone app) or something you are (a fingerprint). Even if a cybercriminal steals a password, they are stopped in their tracks without the second factor.

This method is no longer just for large enterprises; it is a critical control for SMEs. For example, we have seen first-hand how a Hampshire-based financial services firm fortified its client data by mandating hardware security keys for all advisors. Similarly, a local law firm uses Microsoft 365 Conditional Access policies to enforce MFA when staff access client files from outside the office, ensuring GDPR compliance. Its role in preventing unauthorised access cannot be overstated.

How to Implement MFA Effectively

A successful MFA rollout requires a clear strategy to ensure user adoption and minimal disruption. It is a cornerstone of modern security, protecting your organisation's most valuable communication asset.

• Prioritise a Phased Rollout: Begin by enabling MFA for administrator and other high-privilege accounts immediately. Then, plan a gradual deployment for all other users, providing a grace period of 30-60 days to allow everyone to get set up.
• Choose Secure Methods: While SMS is an option, authenticator apps like Microsoft Authenticator or Google Authenticator are more secure as they are not vulnerable to SIM-swapping attacks. Explore the security benefits and considerations by reading more about the safety of two-factor authentication.
• Manage Backup and Recovery: Ensure users securely store their backup codes for emergency access. For administrators, it is vital to have a documented and secure process for account recovery when a user loses their second factor.

Key Insight: For organisations in Dorset and surrounding counties, SES Computers can manage the entire MFA deployment process, from initial policy configuration in Microsoft 365 or Google Workspace to providing end-user support during the transition, ensuring a seamless and secure implementation.

2. DMARC, SPF, and DKIM Email Authentication

Implementing DMARC, SPF, and DKIM is a crucial email security best practice that prevents cybercriminals from spoofing your domain. These three authentication protocols work in unison to verify that an email claiming to be from your organisation is legitimate. SPF lists authorised sending servers, DKIM adds a tamper-proof digital signature, and DMARC sets the policy for how receiving servers should handle emails that fail these checks, effectively slamming the door on impersonation attacks.

These protocols are the industry standard for protecting your brand's reputation and building trust. We have seen their direct impact with Somerset-based accountancy firms, where a robust DMARC policy stopped fraudulent tax return phishing scams targeting their clients. A practical example would be a professional services firm using a third-party marketing platform like Mailchimp; without proper SPF and DKIM records, their marketing emails could be flagged as spam, damaging their reputation and campaign effectiveness. This technical foundation is non-negotiable for modern email security.

How to Implement Email Authentication Effectively

A methodical rollout of these DNS-based records is key to avoiding disruption to legitimate email flow while bolstering your defences. Proper configuration is essential for protecting your clients, suppliers, and internal staff from targeted email fraud.

• Start by Monitoring: Begin by publishing a DMARC record with the policy set to p=none. This allows you to monitor DMARC reports and identify all legitimate email sources without impacting mail delivery.
• Implement SPF and DKIM: Concurrently, create a precise SPF record listing all authorised third-party senders (e.g., your marketing platform, CRM). Then, enable DKIM signing on all your sending services, including Microsoft 365 and Google Workspace.
• Enforce Your DMARC Policy: After monitoring and resolving authentication issues for 60-90 days, gradually strengthen your DMARC policy from p=none to p=quarantine (sends unverified emails to spam) and finally to p=reject (blocks them entirely).

Key Insight: The technical configuration of SPF, DKIM, and DMARC records can be complex, especially with multiple third-party sending services. SES Computers provides expert management for businesses across Wiltshire and Hampshire, handling the precise DNS configuration and ongoing monitoring to ensure your domain is fully protected without blocking legitimate communications.

3. Email Encryption and Data Loss Prevention (DLP)

Email encryption converts sensitive messages and attachments into unreadable code, making them useless if intercepted. Paired with Data Loss Prevention (DLP), which scans outgoing emails for specific confidential data, it creates a powerful safeguard. This combination automatically enforces security policies to prevent accidental or malicious data leaks, a critical control for any professional services firm handling private information.

This proactive approach is essential for maintaining regulatory compliance and protecting intellectual property. For example, we configured Microsoft Information Protection for an accountancy firm in Wiltshire to automatically encrypt any email containing the phrase "tax return" in the subject line or attachment name. Similarly, we helped a recruitment agency secure candidate data by implementing a DLP policy that blocks emails with multiple CV attachments from being sent to personal email addresses.

How to Implement Encryption and DLP Effectively

A well-configured DLP strategy is a core component of modern email security best practices, protecting data both in transit and at rest. It requires a thoughtful approach to policy creation and user education to be successful without hindering productivity.

• Start with High-Risk Data: Begin by creating DLP policies that target your most critical information, such as credit card numbers, national insurance numbers, or sensitive legal documents. Use pre-built templates for common patterns to accelerate this process.
• Automate Encryption: Configure policies to automatically apply encryption to any external email that contains sensitive data. This removes the burden from employees and ensures consistent protection.
• Train Your Users: Educate staff on why certain emails are blocked or encrypted. This understanding helps foster a security-conscious culture and reduces frustration with the system. While active DLP tools protect data in transit, a comprehensive strategy also includes the end-of-life stage. Learn more about creating a policy for secure data destruction for retired physical assets.
• Review and Refine: Regularly review DLP logs and incident reports to identify policy gaps or areas for improvement. Document any exceptions required for legitimate business processes to maintain a clear audit trail.

Key Insight: For businesses in Wiltshire handling sensitive financial or client data, SES Computers can design and implement tailored DLP and encryption policies within Microsoft 365. We manage the entire process, from initial configuration to ongoing optimisation, ensuring your data remains secure and compliant.

4. Advanced Threat Protection and Sandboxing

Advanced Threat Protection (ATP) moves beyond traditional signature-based antivirus to tackle the sophisticated email threats that often bypass standard filters. It uses machine learning, behavioural analysis, and sandboxing to detect and neutralise zero-day malware, advanced phishing, and ransomware. A key component, sandboxing, executes suspicious attachments and links in an isolated, secure virtual environment to observe their behaviour before they can reach a user's inbox, forming a proactive defence against unknown threats.

This technology is a critical email security best practice for any modern business. For instance, we’ve seen a legal firm in Somerset avoid a costly ransomware attack when ATP sandboxing intercepted a malicious macro hidden within a seemingly legitimate court document attached to an email. Similarly, accountancy practices across Wiltshire rely on ATP to detect and block convincing business email compromise attempts that could otherwise lead to fraudulent payments, protecting both their own and their clients' finances.

How to Implement ATP Effectively

A well-configured ATP solution provides a powerful, automated defence layer, but it requires careful setup and ongoing management to maximise its effectiveness and minimise disruption to legitimate business communications.

• Configure Comprehensive Policies: Enable sandboxing for all high-risk file types, including executables, archives, and all Microsoft Office documents with macros. Combine this with URL rewriting and scanning features to check links for malicious content at the time of click.
• Combine with User Training: ATP is most effective when paired with robust security awareness training. Educate staff on how to recognise phishing attempts that might still appear in their inboxes, creating a strong human firewall as your last line of defence.
• Monitor and Fine-Tune: Regularly review ATP alerts and logs to identify patterns that may indicate a targeted attack against your organisation. Use these insights to create specific allow-lists for trusted senders or adjust policies to reduce false positives without compromising security.

Key Insight: For organisations in Hampshire and Dorset, SES Computers provides expert setup and management of ATP solutions like Microsoft Defender for Office 365. We handle the initial policy configuration, ongoing monitoring, and incident response, ensuring your business is protected from the most advanced email-borne threats.

5. Regular Security Awareness Training and Phishing Simulations

Technical controls are vital, but human error remains the leading cause of email security breaches. Regular security awareness training, combined with simulated phishing campaigns, transforms your employees from a potential vulnerability into your first line of defence. This practice educates staff to recognise, question, and report suspicious emails before they can cause harm, fostering a proactive security culture.

This approach creates a dramatic and measurable reduction in risk. A practical example is an accountancy firm in Wiltshire that saw its staff report rate for suspicious emails increase from 10% to over 90% after six months of our tailored phishing simulation programme. This meant malicious emails were being neutralised by staff before they could even be analysed by security systems. For any professional services business, this is one of the most impactful email security best practices for preventing invoice fraud, ransomware, and data loss.

How to Implement Security Training Effectively

A successful training programme is ongoing, engaging, and relevant. It is not a one-time event but a continuous process of education and reinforcement that keeps pace with evolving cyber threats.

• Start with a Baseline: Begin with a phishing simulation to gauge your organisation's current vulnerability. This identifies at-risk departments and individuals, allowing you to tailor initial training efforts where they are needed most.
• Establish a Regular Cadence: Implement at least quarterly training sessions and monthly phishing simulations. Use realistic scenarios relevant to your industry, such as fake client fund transfer requests for a law firm or urgent invoice payment demands for an accounting practice. You can learn more about specific techniques for phishing attack prevention.
• Provide Immediate, Positive Feedback: When an employee fails a simulation, provide instant feedback and a mini-lesson. Focus on positive reinforcement for those who correctly report phishing attempts rather than punishing mistakes, as this encourages engagement.

Key Insight: For SMEs in Hampshire and the surrounding counties, SES Computers designs and manages comprehensive security awareness programmes. We handle everything from baseline testing and customised phishing simulations to ongoing training and detailed reporting, building a resilient security culture for your business.

6. Email Server Patching, Hardening, and Configuration Management

An unpatched and poorly configured email server is a primary target for cybercriminals. This email security best practice combines proactive patch management with system hardening to reduce your organisation's attack surface. It involves keeping your email platform, like Microsoft Exchange or Microsoft 365, updated with the latest security patches while also configuring it to be as secure as possible by default, disabling unnecessary features and enforcing strict access controls.

Neglecting this area can have severe consequences. We have seen first-hand how proactive patching protected our Hampshire-based manufacturing clients from widespread threats like the ProxyShell vulnerability, ensuring business continuity. A practical example for professional services is hardening email configurations for a law firm to prevent staff from setting up automatic forwarding rules to personal email accounts, a common tactic used by malicious actors to exfiltrate sensitive client data.

How to Implement Effective Patching and Hardening

A robust strategy involves regular, scheduled maintenance and a security-first configuration baseline. This ensures your email system is resilient against both known exploits and common misconfigurations that lead to data breaches.

• Establish a Formal Patch Management Policy: Schedule monthly patch deployments, ideally testing them in a non-production environment first. Prioritise critical patches for email systems and provide users with 24-48 hours' notice before deployment to minimise disruption.
• Audit and Harden Configurations: Regularly audit your email configuration against recognised standards like the CIS Benchmarks for Microsoft 365. Key actions include disabling legacy authentication protocols, restricting Outlook rules that allow automatic forwarding to external domains, and limiting PowerShell access to authorised administrators only.
• Maintain Vigilance: Subscribe to vendor security bulletins (like Microsoft's) and monitor CVE databases for new vulnerabilities affecting your systems. Use automated vulnerability scanning tools to identify weaknesses before they can be exploited.

Key Insight: For businesses in Wiltshire and across the South, SES Computers provides a fully managed patching and hardening service. We handle the entire lifecycle, from patch testing and deployment to auditing your Microsoft 365 environment against security benchmarks, ensuring your email platform remains secure and compliant.

7. Email Backup and Disaster Recovery

Email Backup and Disaster Recovery is a critical email security best practice that ensures your organisation can quickly restore communications and maintain continuity after a disruptive event. This involves creating and storing secure copies of your email data, so if servers are compromised by ransomware, suffer hardware failure, or are hit by a cyber-attack, you can recover vital information. A robust strategy protects against permanent data loss and helps meet the availability requirements of data protection regulations like GDPR.

This proactive measure is indispensable for business resilience. We've seen first-hand how our automated cloud backups have enabled a Somerset-based architecture firm to recover three years of project correspondence after a server failure. Another practical example is an accountancy firm in Wiltshire that restored essential financial correspondence deleted by a ransomware attack, allowing them to continue operations without paying the ransom. These scenarios highlight how a solid backup plan prevents a technical issue from becoming a business-ending catastrophe.

How to Implement Email Backup Effectively

A successful backup and recovery strategy is about more than just copying files; it requires a documented, tested, and secure process. It is a fundamental component of operational resilience, safeguarding your communications against unforeseen threats.

• Follow the 3-2-1 Rule: Maintain at least three copies of your data on two different media types, with one copy stored off-site. This classic strategy protects against localised disasters like fire or theft.
• Test Recovery Procedures: Regularly test your ability to restore data from backups, ideally on a quarterly basis. This verifies the integrity of your backups and ensures your team is prepared for a real recovery scenario. You can explore a full strategy in our guide to IT disaster recovery solutions.
• Use Immutable Backups: To counter ransomware, use immutable or air-gapped backups that cannot be altered or deleted by attackers. This ensures you have a clean, uncompromised copy of your data ready for restoration.
• Define Recovery Objectives: Establish a clear Recovery Time Objective (RTO) for how quickly you need to restore service and a Recovery Point Objective (RPO) for how much data you can afford to lose. These metrics will define your backup frequency and technology choices.

Key Insight: For organisations in Dorset and the surrounding counties, SES Computers provides fully managed, UK-hosted automated cloud backup services. We handle the entire process from initial setup to regular testing and monitoring, ensuring your email system is protected and recoverable, providing complete peace of mind.

8. Email Access Controls and Zero Trust Architecture

Implementing robust email access controls through a Zero Trust Architecture is a modern and highly effective email security best practice. This model operates on the principle of 'never trust, always verify', which means it requires continuous authentication and authorisation for all users and devices, regardless of their location. It moves beyond the outdated idea of a secure internal network, treating every access request as a potential threat until proven otherwise.

This approach prevents unauthorised access even if a user's credentials have been compromised. For instance, we have helped an accountancy firm in Wiltshire implement Azure AD Conditional Access policies that block logins from unrecognised devices or any country outside the UK, stopping attackers in their tracks. Similarly, a legal practice uses this model to enforce device compliance, ensuring that only firm-issued, encrypted laptops can access emails containing sensitive client case files.

How to Implement Zero Trust for Email

Adopting a Zero Trust mindset requires a strategic shift from perimeter-based security to identity and device-centric controls. It ensures that only the right people, using secure devices, can access your email system under the right conditions.

• Start with Conditional Access: For Microsoft 365 environments, begin by configuring Azure AD (now Entra ID) Conditional Access policies. These rules can enforce MFA, require compliant devices, or block access based on location, sign-in risk, and application.
• Enforce Device Compliance: Create policies that check the health and security of a device before granting access. This can include verifying that the operating system is up-to-date, that antivirus software like Windows Defender is active, and that the device's storage is encrypted.
• Monitor and Respond to Risks: Actively monitor for high-risk scenarios, such as "impossible travel" where a user logs in from different countries in minutes. Use risk-based authentication to automatically trigger stricter requirements, like a password change or MFA prompt, when suspicious behaviour is detected.

Key Insight: For businesses across Somerset and Hampshire, SES Computers can design and deploy a Zero Trust architecture tailored to your specific needs. We manage the entire process, from setting up Conditional Access policies to monitoring for threats, ensuring your email remains secure in an evolving threat landscape.

9. Email Authentication Monitoring and Threat Intelligence

Implementing email authentication standards is a critical first step, but continuous monitoring is what transforms these static defences into a dynamic, proactive security measure. This practice involves actively analysing email authentication logs (SPF, DKIM, DMARC) and integrating this data with threat intelligence feeds. It allows you to move beyond simply blocking fraudulent emails to actively detecting and responding to sophisticated attacks as they happen, making it a vital component of modern email security best practices.

This approach enables you to spot anomalies, such as a sudden spike in failed authentication attempts from a new source, or to identify if your domain is being used in a widespread phishing campaign targeting your supply chain. For example, for a Dorset-based accountancy firm we support, real-time DMARC monitoring detected an unauthorised third-party service attempting to send emails on their behalf. This allowed us to immediately investigate and block the service, preventing a potential brand-impersonation attack.

How to Implement Effective Monitoring and Intelligence

A successful strategy requires centralising data and establishing clear response protocols. It provides the visibility needed to understand not just what is being blocked, but also who is targeting your organisation and how.

• Centralise and Analyse Logs: Aggregate all email-related logs into a centralised platform, such as a Security Information and Event Management (SIEM) system. This creates a single source of truth for analysing traffic, establishing a baseline of normal activity, and setting up alerts for suspicious patterns like credential stuffing attacks.
• Leverage Threat Intelligence Feeds: Subscribe to high-quality threat intelligence feeds relevant to your industry, such as those from Microsoft, Proofpoint, or Cisco Talos. This enriches your log data with context about known malicious IPs, domains, and emerging ransomware signatures, allowing for a faster, more accurate response.
• Establish Rapid Response Protocols: Create clear, documented escalation procedures for critical alerts, aiming for a sub-15-minute initial response time. Integrating solutions that provide real-time visibility and advanced analytics is key for effective threat intelligence, especially given that email is a frequent vector for insider threats; reviewing the leading insider threat detection tools can offer valuable insights into strengthening this capability.

Key Insight: For organisations that lack a dedicated security operations centre, SES Computers provides a managed 24/7 monitoring service. We handle the integration of threat intelligence, configure alerts for your specific risk profile, and provide the expert analysis needed to respond to threats around the clock, protecting your Hampshire or Somerset business from advanced email-based attacks.

10. Incident Response Planning and Email Security Breach Procedures

Even with the best defences, a security incident can still occur. Effective incident response planning for email security ensures your organisation can react swiftly and decisively to a breach, minimising damage, downtime, and reputational harm. A documented plan provides a clear roadmap for containment, investigation, and recovery, turning a potential catastrophe into a managed event. This proactive approach is a critical component of modern email security best practices.

A well-rehearsed plan is invaluable. A practical example is an accountancy firm in Wiltshire that used its predefined playbook to immediately contain a Business Email Compromise (BEC) attack. The plan dictated immediate steps: reset the compromised user's password, force a sign-out from all sessions, scan for malicious forwarding rules, and notify affected clients within 60 minutes, preventing financial loss and demonstrating professional diligence.

How to Develop an Email Security Incident Response Plan

Creating a robust plan involves defining roles, procedures, and communication channels before an incident happens. This preparation ensures a coordinated and effective response when facing a real-world threat.

• Create Specific Playbooks: Develop step-by-step guides for common email-related incidents like a successful phishing attack, a BEC attempt, or a ransomware infection delivered via email. These playbooks should detail immediate containment actions, such as isolating affected systems or resetting passwords.
• Define Roles and Responsibilities: Clearly assign roles, such as an Incident Commander with the authority to make critical decisions. Ensure everyone on the response team understands their duties, from technical investigation to legal and PR communications.
• Practise with Tabletop Exercises: Regularly conduct simulated incident scenarios to test your plan’s effectiveness. These exercises help identify gaps, clarify procedures, and ensure your team is prepared to act under pressure without hesitation. Document lessons learned to refine the plan.

Key Insight: For businesses in Hampshire and Dorset, SES Computers helps develop and test comprehensive incident response plans tailored to email security threats. We can facilitate tabletop exercises and create actionable playbooks, ensuring your team is fully prepared to handle a security breach efficiently and professionally.

From Checklist to Culture: The True Value of Email Security

Mastering these email security best practices delivers benefits that extend far beyond simply blocking spam or malware. A secure email system is fundamental to maintaining operational integrity, protecting sensitive client data, and upholding your professional reputation. For businesses in sectors like accountancy, law, and financial planning, where data confidentiality is paramount, this is not just a technical requirement; it is a legal and ethical obligation.

Consider the practical implications:

• Enhanced Client Trust: Demonstrating a robust commitment to security assures clients that their confidential information, whether financial records or personal legal matters, is safe in your hands.
• Improved Business Continuity: With solid backup and disaster recovery plans, an email outage or a security incident becomes a manageable event rather than a catastrophic failure that halts operations.
• Stronger Compliance Posture: Proactively implementing controls like encryption and DLP aligns your business with regulatory requirements such as GDPR, simplifying audits and reducing the risk of significant fines.

Ultimately, the goal is to embed security so deeply into your processes and culture that it becomes second nature. It's about empowering your team to be your first line of defence, supported by a technical framework that makes it difficult for attackers to succeed. This creates a powerful synergy where technology and people work together to protect your business.
