You can't defend what you don't know you own.
of cybersecurity incidents in 2025 traced to unknown or unmanaged assets
more assets than they knew about, what organizations typically uncover on first discovery
External risk isn't everything you can seeit's everything attackers can reach
Securin continuously discovers every internet-facing asset you own including the ones you didn't know about and enriches each exposure with weaponization intelligence, so your team fixes what attackers will actually use.
Find shadow IT before attackers do
Continuously discover forgotten dev environments, rogue cloud deployments, and unsanctioned SaaS, no agents, no credentials, no asset list required.
Fix the 1% that's actually exploitable
Weaponization intelligence turns thousands of scanner findings into a short, defensible fix list, ranked by attacker interest, not CVSS alone.
De-risk M&A before the deal closes
Agentless, credentialless visibility into a target or subsidiary's external footprint, due diligence the board can act on, before and after close.
Extend visibility to third parties
Monitor vendor-facing infrastructure and brand domains under a single attribution model, without waiting on questionnaires.
Connect leaked credentials to attack paths
Dark web credentials tied to your domains, correlated to the exact internet-facing asset they could unlock. The alert and the attack path, in one view.
Prove control to boards and insurers
Continuously updated, defensible evidence that your external perimeter is monitored, managed, and de-risked, ready for any governance review.
SHADOW IT DISCOVERY
The asset you forgot is the asset they'll find.
Acquisitions, cloud sprawl, and unsanctioned tools create infrastructure your CMDB has never heard of. Attackers don't need your asset list to find it, they scan the internet, same as we do.
- Continuous, outside-in discovery of domains, subdomains, IPs, cloud assets, and exposed services, mapped to your organization automatically
- New and changed assets flagged the moment they appear, not at the next quarterly audit
- Attribution confidence scoring, so you validate real findings instead of chasing false positives
EXPOSURE PRIORITIZATION
Stop ranking by severity. Start ranking by attacker interest.
Scanners return thousands of findings, and CVSS treats a theoretically severe bug the same as one being exploited by ransomware groups this week. Teams burn cycles on vulnerabilities no attacker will ever touch.
- Every exposure enriched with weaponization context: active exploitation, exploit availability, ransomware association, threat-actor usage
- A prioritized fix list your team can actually finish
- Analysts identify the shift from asset identification to risk prioritization as the defining maturity step for EASM programs
CREDENTIAL EXPOSURE
A leaked password plus the asset it unlocks is an incident waiting to happen.
Breach-credential feeds tell you an email and password leaked. They don't tell you whether that credential opens a VPN portal, an admin panel, or nothing at all, so triage stalls.
- Continuous monitoring for breached credentials tied to your domains
- Each credential correlated to the specific internet-facing asset it could unlock
- The alert and the attack path in one view, so response is immediate and targeted
How Securin Surface works
Built on the same passive reconnaissance techniques real adversaries use, backed by original vulnerability research.
Continuous outside-in discovery
Seed-based pivoting across DNS, SSL/TLS certificate transparency, WHOIS, and BGP. Passive-first by default; optional active probing for service-level visibility on owned assets.
Shadow IT and acquisition-inherited assets surface as they appear, not on a scan schedule.
Multi-signal attribution & hierarchical ownership
Combines certificate metadata, WHOIS ownership, DNS topology, and registrant pivoting. Parent, subsidiary, and acquired-entity views with per-business-unit reporting.
Powers M&A due diligence, subsidiary monitoring, and brand-domain visibility under one ownership model.
Exposure assessment
Surfaces exposed services and management interfaces (RDP, SSH, admin consoles, cloud storage), identifies end-of-life software, and detects expired, self-signed, or weak-cipher certificates.
Flags the obvious external weaknesses before adversaries scan for them.
Weaponization-verified threat enrichment
Securin's CNA-sourced vulnerability research annotates each exposure with exploitation evidence, in-the-wild observation, ransomware association, and threat-actor context.
Analysts work the small set attackers are actually using, not the long CVE tail.
Dark web credential monitoring
Continuous monitoring of deep and dark web sources for breach credentials tied to your domains, correlated to the corresponding internet-facing asset.
Flags the credentials adversaries already have, before they're used against your perimeter.
OUTCOMES
Outcomes you can hold theplatform accountable to
Not features, the results you'll answer for in front of the board.
What you get:
Know every internet-facing asset, including the ones nobody provisioned.
Fewer open, risky services, not just fewer CVEs on a list.
Prioritized, owner-attributed findings that flow to the right team automatically.
A defensible view of true external risk posture, expressed in business terms.
Clean due diligence without agents or credentials.
Continuous evidence the external perimeter is monitored and managed.
A measurable, shrinking count of unmanaged internet-facing assets.
Know every asset. Fix what matters.
