TrustLayer as a Proofpoint alternative.
Proofpoint is enterprise email security, and it's good at it. This page is for UK organisations of 100 to 5,000 people paying enterprise prices for an enterprise stack and using a fraction of it. And for anyone who needs web and cloud app control alongside email, which Proofpoint doesn't sell.
Four real differences.
Proofpoint's customers are the FTSE 100 and the Fortune 500, and the product reflects it: depth, configurability, and an administrative surface that assumes someone owns it full-time. If you have a security team, that's an asset. If email security is a third of one person's job, it's overhead you pay for twice, in licence and in hours.
Worth knowing: Proofpoint completed its $1.8bn acquisition of Hornetsecurity in December 2025 and now runs it as the division leading its SMB and MSP strategy. So there is a Proofpoint answer for organisations your size. It's a separately acquired product line, with its own console and its own roadmap, rather than the platform the rest of the page is about. Ask which one you're being quoted.
This is the clearest gap in the comparison, and it runs in our favour.
Proofpoint protects email, cloud apps and collaboration tools, and enforces URL policy at click time inside the browser. What it does not sell is web security: no secure web gateway, no web filtering, no DNS filtering. Its standalone browser isolation product no longer appears in the product navigation, with that URL now redirecting into the Collaboration Security bundle.
So if you need web filtering, cloud app discovery or control over which AI tools your staff use, Proofpoint is not the vendor for that layer. You buy it somewhere else, manage it somewhere else, and reconcile two sets of policy.
TrustLayer Browse is web security, CASB and AI Exposure on the same platform and the same policy model as Mail. From the device, no proxy.
Indicative, at 750+ users, annually.
Mail, Browse, Users and Posture, priced per user per layer, bought through BT, an MSP or a reseller on a contract you already have. Add a layer and the platform already knows about it.
Proofpoint publishes no list pricing. TrustLayer publishes indicative per-user pricing on the site. Mail is from £2.70 per user per month at 750+ users, billed annually.
Ask about your archive.
If you're on Proofpoint Archive, raise this in the first conversation, with us or with anyone else.
Bulk extraction from an incumbent archive is routinely the hardest, slowest and most expensive part of a switch, and the answer differs by contract, encryption model and volume. We would rather establish what's achievable for your specific archive at the start than discover it three months into a migration.
So: before you commit to any email security change, find out what your exit from Proofpoint Archive actually looks like. If the answer turns out to be that your data is effectively stuck until your retention obligation expires, the sensible plan is a new email security layer alongside the existing archive, rather than a migration. We'll tell you that if that's what we find.
Where the rows separate.
Both deploy without MX changes, both offer CASB, and both cover out-of-hours. Proofpoint wins on telemetry scale, insider threat and analyst recognition. The web and platform rows are where the decision sits for organisations of your size.
