Stop phishing, business email compromise and malicious attachments before they reach your team. DMARC, DKIM and SPF configured correctly from day one.
Phishing was behind 93% of successful cyber attacks on UK businesses in 2025, according to the government's Cyber Security Breaches Survey. Email is the primary attack vector — and for most small businesses, it is the least protected part of their digital infrastructure. Our email security service stops malicious content before it reaches your team and ensures your domain cannot be spoofed to attack your clients.
Phishing. Emails designed to trick recipients into clicking malicious links, entering credentials on fake login pages or downloading infected attachments. Modern phishing emails are increasingly convincing — AI is being used to personalise attacks at scale, making generic awareness training insufficient on its own.
Business Email Compromise (BEC). An attacker gains access to or convincingly spoofs a business email account and uses it to redirect payments, request sensitive data or impersonate senior staff. BEC attacks cause significant financial losses and are often discovered only after money has already moved.
Malicious attachments. Documents, PDFs and compressed files containing malware that executes when opened. Attackers routinely use file types that appear legitimate and pass basic security checks.
Domain spoofing. Attackers send emails that appear to come from your domain — targeting your clients, suppliers or staff. Without proper email authentication in place, your domain can be used to attack people who trust you.
Advanced spam and phishing filtering. Emails are analysed before delivery using multiple detection techniques — reputation checks, link analysis, sandboxing of attachments and behavioural indicators. Malicious content is blocked before it reaches your team's inbox.
Malicious link and attachment scanning. Links are checked at the point of click, not just at delivery — catching threats that activate after initial scanning. Attachments are detonated in a sandbox environment to detect malware that evades static analysis.
DMARC, DKIM and SPF configuration. These three email authentication standards are the foundation of domain protection. Correctly configured, they prevent your domain from being used to send phishing emails and provide you with visibility of any attempts to abuse it. Our free security tools will check your current configuration instantly.
Business Email Compromise protection. We monitor for indicators of account takeover, unusual sending patterns and authentication anomalies that suggest a compromised account — and alert you before damage is done.
Simulated phishing training campaigns. We send controlled phishing simulations to your team, measure who clicks and provide targeted training based on the results. Repeated simulation combined with training reduces click rates significantly and builds genuine awareness rather than just box-ticking.
SPF, DKIM and DMARC are three complementary DNS records that verify your email is legitimate and prevent others from sending email that appears to come from your domain.
SPF specifies which servers are authorised to send email on your behalf. DKIM adds a cryptographic signature to outgoing email that receiving servers can verify. DMARC ties the two together and tells receiving servers what to do with email that fails — reject it, quarantine it or let it through — while sending you reports of any activity.
Many small businesses have SPF in place but no DKIM or DMARC, or have DMARC set to monitoring mode rather than enforcement. That leaves your domain exposed. We configure all three correctly and move you to a policy that actively blocks spoofed email rather than just monitoring it.
Email security is relevant to every business that uses email — which is every business. It is particularly important for organisations that handle client payments or financial instructions, operate in sectors where email impersonation could cause serious harm, use automated email workflows as part of their operations, or have staff working remotely where email is the primary communication channel.
If you use our admin automation or lead capture services, email security is a natural complement — protecting the automated workflows that keep your business running.
Our free email security tool checks your SPF, DKIM and DMARC configuration instantly and tells you what needs fixing. No signup required, results in 30 seconds.

What is DMARC and do I need it?
DMARC is an email authentication protocol that tells receiving mail servers what to do with email that fails SPF or DKIM checks — including email sent by attackers spoofing your domain. Without it, anyone can send email that appears to come from your address. The April 2026 Cyber Essentials update also reinforces email authentication as a baseline control. Our free tool will check whether yours is configured correctly.
We already have Microsoft 365 or Google Workspace — do we still need email security?
Microsoft 365 and Google Workspace include basic spam filtering, but their default configurations leave gaps — particularly around advanced phishing, BEC detection and DMARC enforcement. Our service layers on top of what you already have, adding the detection capabilities and configuration rigour that the platforms do not provide out of the box.
What is a simulated phishing campaign and how does it work?
We send controlled phishing emails to your team that look like real attacks but are safe. We measure who opens them, who clicks links and who reports them. The results give you an accurate picture of your team's current awareness and tell us where to focus training. Campaigns are repeated over time to track improvement.
How long does it take to set up email security?
Basic email authentication (SPF, DKIM, DMARC) can typically be configured within a day once we have access to your DNS. Full email filtering deployment depends on your email platform and the size of your team but most SME deployments are live within a week.
Can you help if we have already been compromised through email?
Yes. If you suspect an account has been compromised or you have received reports that emails are being sent from your domain without your knowledge, contact us immediately. We can assess the situation, contain any ongoing threat and implement the protections needed to prevent recurrence.
Email is the most common entry point for attackers, but not the only one. Penetration testing uncovers weaknesses across your wider network, and 24/7 monitoring detects threats that get through any perimeter — including your inbox.
