Email Security for London Businesses
Email remains one of the main ways malware, phishing and spam reach your users. The content below explains how we filter and control that traffic so it doesn’t reach inboxes in the first place.
With all the sophisticated programs around, viruses and spam are a thing of the past, right? Wrong! They continue to evolve, with new threats appearing daily, threatening to swamp your business or put your computers out of action.
What’s the solution? Careful vigilance by staff will help, but it isn’t enough.
At HTL, we process thousands of messages every day that either contain viruses or are junk mail (spam). Statistics show that around 90% of all email traffic coming through our servers falls into one or other undesirable category.
HTL recommends and supplies two different email security systems. Our basic solution costs as little as £1 per user per month, but for a more advanced solution we recommend Mimecast. Mimecast provides a single integrated suite of email security, archiving and continuity services and reduces the risk, cost and management overhead associated with an array of third-party point solutions – in one service and in the cloud. Mimecast costs as little as £5 per user per month.
Management is easy – you can view and control the quarantined messages for your entire organisation through one easy-to-use web-based management console, even if you have multiple domains.
How Does Email Security Work?
HTL will help you set up an SPF (Sender Policy Framework) record for each of your domains. This helps prevent spammers from impersonating your email address. One benefit of SPF is that the legitimate owners of forged e-mail addresses can be swamped by large quantities of error messages and other auto-replies. Email receivers who check SPF can reject forgeries, thus reducing or eliminating the amount of backscatter.
Additionally, an SPF-protected domain is less attractive to spammers and phishers, because the spoofed address is more likely to be spotted and rejected by spam filters. A protected domain, therefore, is less likely to be blacklisted by spam filters and legitimate e-mail is more likely to get through.
HTL will help you implement the latest developments in TLS (Transport Layer Security) to ensure email privacy and integrity. The TLS protocol allows client/server applications to communicate across a network in a way designed to prevent eavesdropping and tampering. HTL will check your web browser supports TLS and, if required, help you set up a TLS connection.
These controls are managed alongside our Cyber Security Services, SSL Certificates and Hosted Exchange so identity, transport and mailbox protection work together.

Frequently Asked Questions
How quickly can you get email security up and running?
In many cases we can have basic email security and spam filtering up and running within hours, especially if you’re using common cloud email platforms. More advanced configurations can take a little longer, but we always plan changes to avoid disruption.
Will legitimate emails be blocked or go missing?
No system can guarantee 0 false positives, but we tune filtering carefully and give you easy access to a quarantine so you can release messages if needed. Over time we refine settings based on your organisation’s specific traffic and senders.
Do users have to log into another portal to check spam?
That depends on the solution you choose. Some platforms send daily spam digests; others provide a self-service portal. We’ll recommend an approach that fits how your staff prefer to work and your admin model.
Can you protect us against phishing and impersonation emails?
Yes. We use technologies such as SPF, DKIM and DMARC, plus advanced filtering, to reduce impersonation and phishing attacks. We also recommend pairing this with HR Policies and Security Training so users know how to spot suspicious messages.
Does email security work with Microsoft 365 and Hosted Exchange?
Yes. Our email security solutions integrate with Microsoft 365, Hosted Exchange and other common platforms, and are managed alongside your wider Cyber Security Services.
