Peerless Software Software for the people who need to know.
We build security tools and publish original research alongside them. The work and the writing inform each other.
Peerless Software is a small, independent security company. We build security tools and publish original research. The two inform each other.
What we ship and what we publish share the same shape: specific, verifiable, and useful to people doing similar work.
Notes from the work.
We publish what we find. Vulnerability writeups, notes on patterns we keep seeing, and the occasional company post.
Peerless Software is small, independent, and based in the United States. We build security tools for organizations that need to know what's happening on their property, in their traffic, in their accounts.
Alongside the products, we publish writing on what we find while we build. Vulnerability writeups, methodology notes, and the occasional company update. No platform speak. No content marketing.
The people doing the watching deserve better tools. Better tools come from people who do the work themselves.
