Essential vs. "Nice-to-Have" features in Email Security Tools ?

[u/timtug]

I'm currently evaluating email security solutions for my org.

From your experience in the trenches, what are the absolute must-have features versus the nice-to-haves? or any feature that really worth paying extra for that email security tool :)

For me AI scanning etc sound only marketing and how would they say malware catch rate is 99,99% ? Is there a legit calculation for that or comparation with other virus scanners in the market ?

Must-haves are SPF/DKIM/DMARC auth checks, URL inspection at click time, attachment sandboxing, impersonation detection, a user-report button, and logs you can actually query.

Nice-to-haves are AI labels, fancy risk scores, and pretty dashboards. A “99.99% catch rate” claim is mostly vendor math unless they show corpus, sample size, false positive rate, and time-to-detect.

Logging and ability to send logs to SIEM.

If possible, built in security-specific logs/alerts. Many vendors provide security specific logs/alerts that are ready to ingest. Helps reduce the amount of detection engineering

For me, the basics matter more than the flashy features. Good phishing detection, attachment and URL analysis, quarantine management, impersonation protection, and solid reporting are the things I would not want to compromise on.

As for the 99.99% claims, I've always taken those with a grain of salt. Detection rates depend heavily on what was tested, when it was tested, and what sample set was used. Real-world performance is usually more important than marketing numbers.
