See your attack surface the way an attacker does.
HexaSentra continuously discovers everything you expose to the internet, safely tests the apps you authorize for real vulnerabilities, and tells you what to fix first — every finding backed by evidence you can check.
You can't defend what you can't see — and scanners bury the rest in noise.
Mergers, cloud expansion, and distributed teams create assets nobody remembers owning. Traditional scanners then flood you with thousands of "maybes." HexaSentra takes the opposite stance: find everything, then prove what's real.
Human-grade signal
We cross-reference assets and versions to confirm an exposure is legitimate before it ever reaches your team. Only what's real gets your attention.
Evidence for every claim
Each finding carries the artifact that produced it — the response, the record, the certificate — stored immutably. Verify the reasoning; don't take it on faith.
Explainable risk
Every score shows its arithmetic. Confidence multiplies, it never pads the number — so you can defend a priority in a board meeting, not just a dashboard.
Discovery and dynamic testing, one platform.
Discovery, validation, and monitoring across every asset an attacker could reach — proven wherever it lives, not just where it was easy to find.
Continuous asset discovery
Subdomains, IPs, cloud services, certificates, ports, and technologies — mapped and re-mapped as your surface changes.
Ownership attribution
Probabilistic, evidence-anchored attribution tells you which assets are genuinely yours — and never counts the ones that aren't.
Exposure validation
Each detection is tested with a disproof control. A finding is only confirmed once we've tried to prove it false and failed.
Subdomain takeover
Dangling-DNS detection across 40+ providers, confirmed against each provider's own unclaimed-resource fingerprint.
Cloud & storage exposure
Publicly readable buckets and misconfigured cloud endpoints, surfaced before someone else finds them.
Data-leak & secret discovery
Credentials in client JavaScript, exposed .env and source, and other leaks — gathered into one view your team can act on.
Screenshots & change monitoring
A visual gallery of your live surface and a feed of what changed — new hosts, moved services, fresh exposures.
DAST — dynamic app testing
On assets you authorize, we safely test running apps for XSS, SQLi, SSRF, SSTI, LFI, open redirect, CORS and CRLF — non-destructive, confirmed against a control, never fired at unauthorized targets.
Live exploit intelligence
CISA KEV and EPSS overlaid onto your findings, so a known-exploited CVE on a reachable asset rises to the top.
AI & agent access
A first-class API and MCP server let your own AI agents query the surface directly — security you can automate against.
Built to be trusted, not just to alert.
Only what's real reaches you
Validation by disproof means confirmed findings are ones we tried and failed to refute. Your queue is signal, not a scanner's guesses.
Every claim has an artifact
An evidence-anchored, content-addressed graph stands behind each finding. Nothing is asserted from inference alone.
Risk you can explain
A transparent, multiplicative score with confidence caps — so priorities hold up to scrutiny from engineers and executives alike.
From authorized scope to verified fix.
Discover
Map every internet-facing asset from the outside in — no agents, nothing to install.
Attribute
Confirm what's yours with evidence, and set aside what isn't.
Validate
Run a disproof control on each detection to separate real exposure from noise.
Prioritize
Rank by explainable risk, weighted by live exploit intelligence.
Remediate
Fix, then re-verify automatically — a regression re-opens itself the moment it returns.
Manual pentesting, on demand.
When automation isn't enough, our researchers run deep manual penetration tests, red-team engagements, and secure code reviews — the same practitioners behind the platform, validating what matters most by hand.
Priced for hunters and teams alike.

Questions, answered.
What is attack surface management?
Attack surface management (ASM) is the continuous discovery and monitoring of everything your organization exposes to the internet — domains, subdomains, IPs, cloud services, certificates and the technologies running on them — so exposures are found and fixed before an attacker uses them.
How is HexaSentra different from a vulnerability scanner?
A scanner lists potential issues. HexaSentra validates each one with a disproof control before it reaches you, scores it with an explainable model, and attaches the evidence artifact behind every claim — so you act on what's real instead of triaging noise.
Do I need to install an agent?
No. HexaSentra works from the outside in — the same vantage point an attacker has. You authorize your scope and we discover and monitor it continuously, with nothing to deploy on your hosts.
How fast do I see results?
A first scan maps your external surface within minutes of authorizing scope, and continuous monitoring surfaces new assets and exposures as they appear.
Is scanning safe and authorized?
Yes. Every active check is gated behind explicit, verified scope authorization and is non-destructive by design. We never test an asset you haven't authorized.
