Email Security Services For Businesses in London

We configure email retention settings in line with the relevant regulatory requirements and best practice guidance applicable to your sector, ensuring emails are retained for the appropriate periods, that retention policies are applied consistently and that nothing is kept longer than necessary. If your sector has specific retention requirements (legal, financial and healthcare are common examples), we factor those in from the outset.

Microsoft Defender for Office 365 is primarily an anti-virus and endpoint protection tool. It is valuable, but it is not specifically designed to function as a dedicated email security gateway. A specialised email security solution sits in front of your inbox and actively filters incoming traffic for spam, phishing attempts and malware before it ever reaches your users. These are two complementary layers of protection, not alternatives to each other. Relying on Defender alone leaves meaningful gaps that a purpose-built email security solution is designed to cover.

Business Email Compromise and CEO fraud are among the harder threats to defend against technically, because they often rely on social engineering rather than malware. Filters alone will not stop them. Effective protection requires a combination of strong technical controls and well-embedded user habits.

On the technical side, we implement advanced email filtering and configure DMARC, DKIM and SPF records to reduce the risk of spoofed or impersonated emails reaching your inbox. On the human side, we provide security awareness training to help your team, particularly executives and those handling payments or sensitive information, recognise the warning signs and know what to do when something looks suspicious. No single measure eliminates the risk entirely, but a layered approach puts you in the best possible position.

Yes. The core security standards we apply are consistent across all clients; phishing, malware and spam need to be stopped regardless of sector. But within that, filtering can be configured to reflect the specific needs of your business.

A law firm may need more stringent controls to protect sensitive client information. A recruitment business needs to ensure CVs and speculative emails from candidates are not incorrectly caught by filters. We configure and tune your email security to reflect these realities, and continue to adjust it over time based on what the data shows.

Yes. DMARC, DKIM and SPF setup is something we offer as a dedicated project. These three DNS-based records work together to authenticate outbound email from your domain, making it significantly harder for attackers to impersonate your business in phishing or spoofing campaigns. If these are not currently configured correctly for your domain, it is worth addressing. It is one of the more impactful and relatively straightforward security improvements you can make.

For the most part, implementation happens in the background with minimal disruption to your team. The main adjustment period comes in the first few weeks, when the filtering system is learning your environment. During that time, occasional legitimate emails may be caught by the spam filter. This is normal and expected.

You will receive spam filtering reports regularly, so you can see what is being caught and flag anything that should not be. We use that feedback to fine-tune the sensitivity of the filters over time. The system improves as it learns, and once calibrated to your environment, it becomes increasingly effective with very little ongoing effort from your team.
