Who Is This For

When can you use it

Built for the moment you are about to commit to a security vendor and need confidence in the decision you are about to make.

You are evaluating vendors across EDR, IAM, SIEM, Email, Network, or Cloud security and need a clear, defensible path forward.
You are about to commit £100K+ and aren’t fully confident the recommendation will hold up to scrutiny.
You don’t fully trust vendor claims and want them assessed against independent benchmarks, not marketing materials.
You need something structured and source-referenced that you can take to leadership — with an audit trail, not just an opinion.
You are in a mid-market organisation without access to Gartner-level analysis — or you need a faster, decision-specific view.
You want a second opinion before you sign — one that surfaces risks and costs you may not have considered.
The Cost of Getting It Wrong

A wrong decision isn’t
just expensive — it lingers.

VendorVerdict
A recommendation you can justify — with evidence, not opinion.
Most decisions rely on vendor briefings, analyst summaries, and incomplete cost visibility. VendorVerdict surfaces trade-offs and risks clearly, before you commit.
Source-referenced · Auditable · Vendor-neutral
No commercial relationships with any security vendor in our dataset. Every score references publicly verifiable data — MITRE evaluations, published pricing, and independently sourced market analysis.
