12 Serverless Security Options Compared (2026): Features & Pricing
A buyer-focused comparison of twelve serverless security offerings concludes no standalone SKU is worth buying in 2026, with function protection bundled inside CNAPP contracts.
The scorecard compares twelve serverless security options on function-protection depth, pricing visibility, platform attach economics, multi-runtime coverage, and vendor viability. Microsoft Defender for Cloud tops the weighted scores at 4.75, with Prisma Cloud at 4.60 and Datadog at 4.55 noted for publishing clean per-function rates. The piece warns that Thundra and Epsagon are defunct and that most vendors bill functions inside platform units where costs are hard to see. It also references the Aqua Security Trivy supply chain incident and Google's finalized acquisition of Wiz as market context.

Terminated employee cost company hundreds of thousands of dollars because nobody revoked access
A terminated employee's unrevoked access let him delete files and corrupt a database, costing the company hundreds of thousands of dollars and weeks of delays.
The Register's PWNED column recounts an anecdote from Yad Senapathy, CEO of the Project Management Training Institute, about a company with 1,000+ employees where a terminated employee's credentials were never revoked. The former worker retained shared admin credentials and used them to delete files, lock accounts, and corrupt a database, causing hundreds of thousands of dollars in damage and weeks of project delays. The takeaway is that unclear offboarding responsibility and unreviewed admin access enabled the sabotage.
