How to evaluate any email security vendor

Four questions worth asking every vendor on your shortlist, including us.

Test it on live mail, not a corpus

Retro-scanning an old archive proves a tool can recognise attacks that already have signatures. Ask for a proof of concept on the mail arriving today.

Ask why, not just what

A risk score is not a reason. Every verdict should carry reasoning an analyst can read, audit and disagree with.

Count the false positives

A high catch rate is easy to hit if you quarantine aggressively. The hard part is a high catch rate at under 1% false positives.

Time the deployment honestly

Ask how long until it is protecting production. API connection in 15 minutes, no MX record changes, no migration project, no downtime.

“Inbox Advisor saves my department hours every week by cutting down triage time on every alert, while the SOC dashboard shows exactly what my team needs at a glance. StrongestLayer is that rare tool that is both incredibly powerful and genuinely well-designed.

“StrongestLayer helps us in the areas where our users have fallen short. Using an AI model to detect and quarantine phishing emails is far better than relying on the user to catch them.
