As answered by people managing SentryScore and CodeSignal.
SentryScore's answer
Most security tools either cost thousands a month or require a security expert to interpret the results. SentryScore is different on both counts.
SentryScore's answer
The biggest competitors in this space — SecurityTrails, Qualys, Nessus — are enterprise tools priced and designed for enterprise teams. SentryScore is built from the ground up for the opposite end of the market.
If you're a Fortune 500 with a security team, use Qualys. If you're a 10-person law firm trying to understand your exposure, SentryScore was built for you.
SentryScore's answer
SentryScore is built for small business owners and operators who are not security professionals — specifically:
The common thread: they know security matters, they’ve probably been asked about it, but they don’t have an IT department or a CISO. They need answers fast, in plain English, without a six-figure contract.
SentryScore's answer
SentryScore was built out of a recurring frustration.
Grant Heckman, the founder, has spent years in cybersecurity working with enterprise clients. When friends and family would ask “Am I secure?” or “My insurance company is asking about my security posture — what do I even say?” — there was no good answer to point them to. Enterprise tools were overkill. Free tools were either useless or so technical they created more confusion than clarity.
SentryScore started as an internal tool to quickly assess a domain's security health for SMB clients. After seeing how much value it delivered in seconds versus hours of manual work, we built it into a product anyone could use.
The name reflects the mission: give every business a score they can understand, track, and act on — the same way a credit score made personal finance legible to everyone.
SentryScore's answer
SentryScore is built on a modern, lightweight stack optimized for speed and reliability:
SentryScore's answer
SentryScore launched in early 2026. We're in early growth — users include small medical and dental practices, independent law firms, and accounting offices that have used the free scan to assess their domain exposure before a vendor audit or cyber insurance renewal.
We don't name client names publicly at this stage, but our target segment is SMBs with 1–50 employees in regulated industries (healthcare, legal, financial services) who need a quick, credible answer to the question: "How secure are we?"
