Email Security in Exeter
Securing email for Exeter organisations, which is where most successful attacks begin. Two distinct problems sit here — stopping malicious mail arriving, and stopping criminals sending mail that appears to come from you — and organisations usually address the first while leaving the second entirely open.
Why this comes up
The problem
Phishing reaches staff inboxes regularly, and customers have reported emails appearing to come from the company that nobody sent.
What you get
What we deliver
- Filtering tuned to your mail rather than left at defaults
- SPF, DKIM and DMARC configured, so your domain cannot be trivially spoofed
- DMARC moved to enforcement, since monitoring alone stops nothing
- Impersonation protection for the names attackers actually use — directors, finance
- External sender marking, which helps staff spot what came from outside
- Multi-factor authentication on all mailboxes, since credentials are the target

Email Security in Exeter — common questions
- Why do people receive emails claiming to be from us?
- Because without properly enforced SPF, DKIM and DMARC, anyone can send mail claiming your domain. This is how invoice fraud against your customers usually starts, and the fix is configuration rather than a purchase.
- What does DMARC enforcement mean?
- Moving from monitoring to instructing receiving servers to reject or quarantine mail failing authentication. Many organisations configure DMARC in monitoring mode and stop there, which produces reports and blocks nothing. Enforcement is the step that matters.
- Which attacks actually succeed?
- Impersonation of people, not brands. A message appearing to come from a director asking finance to process a payment, or from a supplier changing bank details. These carry no attachment or link for a filter to catch, which is why staff awareness matters alongside filtering.
- Is the built-in filtering enough?
- For many organisations, properly configured, yes — Microsoft 365's protection is capable but frequently left at defaults. Tuning what you have is worth doing before buying an additional layer to compensate for configuration nobody completed.
- Do you work with businesses across Devon?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout South West, including Exeter and the surrounding Devon area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Exeter businesses do you usually work with?
- Field service scheduling and routing for businesses covering a wide rural patch, plus professional services systems. Beyond that we work across Higher Education, Professional Services, Healthcare, Retail and Environmental Science.
- Do you cover the areas around Exeter?
- Yes — we work throughout South West, including Plymouth, Truro, Bristol. Exeter is an urban area of roughly 130,000+, and we take on work across the wider Devon region rather than the city boundary alone.
