Identity Security — the credential is now the perimeter.
39% of breaches involve stolen credentials, and 73% of ransomware victims had an infostealer infection or credential leak in the year before the attack. SIRI's identity security capability tests and monitors the access paths attackers actually use.
A firewall doesn't stop an attacker who's already logged in
39% of breaches don't need an exploit. They need one valid, stolen credential.
Identity has quietly become the primary control boundary in most modern environments — more consequential in practice than network perimeter controls, because a valid credential lets an attacker in through the front door rather than requiring them to find a technical flaw. Testing and monitoring that boundary means going well past password policy: privileged-access review, credential-exposure monitoring, and testing what a compromised identity can actually reach.
The data makes the pattern explicit: 73% of ransomware victims had an infostealer infection or credential leak in the prior year, with a median gap of just 95 days between the leak and the attack. Password reuse compounds the problem — users are four times more likely to reuse a compromised password than to adopt a weak one, meaning a single leaked credential frequently unlocks more than the system it was stolen from.
SIRI's identity security capability monitors for credential exposure, reviews privileged access and identity architecture for excess permission, and tests what an attacker with a single compromised identity could actually reach — feeding findings into SIRI Exposure for continuous tracking and SIRI Attack for full attack-path validation.
What organisations get wrong
Four assumptions that leave identity the weakest link
Most identity security gaps aren't about weak passwords — they're about what a valid credential is allowed to reach.
“We enforce strong password policy”
Password strength doesn't prevent credential theft via phishing or infostealer malware — 39% of breaches involve stolen credentials regardless of how strong the original password was.
“We have MFA, so we're covered”
Partial MFA coverage leaves gaps — the accounts left uncovered are frequently the ones with the most access, and session-token theft can bypass MFA entirely.
“Access requests are reviewed when granted”
Access reviewed at grant time and access reviewed continuously are different — permissions accumulate and go stale as roles change, quietly expanding what a compromised account can reach.
“We'd know if our credentials were leaked”
Without active dark-web and credential-leak monitoring, a leaked credential is typically discovered only when it's already been used against you.
What SIRI's identity security covers
From credential exposure to what a compromised identity can actually reach
Monitoring, review and testing, connected into one identity-risk picture.
Credential-Exposure Monitoring
Continuous monitoring for leaked credentials and exposed secrets across the dark web and public sources.
- Leaked-credential monitoring
- Exposed API-key & secret detection
- Early-warning alerting
Privileged-Access Review
Reviewing who holds privileged and administrative access, and whether it's still justified.
- Privileged-account inventory
- Access-recertification review
- Stale-permission identification
Identity Attack-Path Testing
Testing what a single compromised identity could actually reach across your environment.
- Privilege-escalation path testing
- Lateral-movement testing
- Cross-system access-path mapping
Zero-Trust & Least-Privilege Design
Designing identity architecture around least privilege, so one credential can't reach everything.
- Zero-trust architecture guidance
- Least-privilege design review
- Segmentation recommendations
MFA & Session-Security Review
Reviewing MFA coverage gaps and session-token handling that can otherwise bypass MFA entirely.
- MFA-coverage gap analysis
- Session-token security review
- Phishing-resistant MFA guidance
Identity-Specific Detection
Detection tuned to identity-based attack patterns, not just network-layer anomalies.
- Anomalous-access detection
- Impossible-travel & behaviour analytics
- Feeds SIRI MDR
Evidence, not guesswork
No identity security programme vs. password policy alone vs. SIRI Identity Security — what actually differs
A password policy and a tested identity-security posture are different things.
| Approach | No identity security programme | Password policy alone | SIRI Identity Security |
|---|---|---|---|
| Credential-leak monitoring | No | No | Continuous |
| Privileged-access review cadence | None | At grant time only | Continuous recertification |
| Identity attack-path testing | No | No | Included — via SIRI Attack |
| MFA & session-security review | No | Basic enforcement only | Full gap analysis |
| Identity-specific detection | No | No | Tuned via SIRI MDR |

Numbers every board should know
What identity risk actually looks like
Of breaches involve credentials
Stolen credentials somewhere in the attack chain (2026 Verizon DBIR).
Ransomware had a leak first
Of ransomware victims had a prior infostealer infection or credential leak.
Higher reuse risk
Users are four times more likely to reuse a compromised password than a weak one.
Median warning window
Between a credential leak and the ransomware attack that followed.
Compliance alignment
Standards & frameworks we align to
Our methodology is built around publicly recognised frameworks — not a proprietary checklist. Where a specific certification or attestation is completed and verified, it will be named here explicitly.
Framework references reflect publicly available versions as of publication and describe the standards our methodology is aligned to; they are not a claim of certification, attestation, or audit completion unless stated explicitly elsewhere on this site.
Why SIRI for identity security specifically
Testing what a credential can reach, not just how strong the password is
Identity risk compounds quietly across systems — testing has to follow the access path, not just the login screen.
Monitoring connected to testing
Credential-leak monitoring feeds directly into identity attack-path testing, so exposure and exploitability are assessed together.
Follows the access path
Testing traces what a compromised identity could actually reach across systems, not just whether the login itself is protected.
Built on real breach data
Coverage priorities are grounded in current breach data showing where credential-related risk actually concentrates.
Connected to detection
Findings feed into SIRI MDR for identity-specific anomaly detection, closing the loop from exposure to monitoring.

OngoingFrequently asked
Identity security, answered directly
How is this different from just enforcing MFA?
MFA is one control among several — this capability also covers credential-leak monitoring, privileged-access review and testing what a compromised identity can actually reach, since session-token theft and MFA-coverage gaps can bypass MFA alone.
Do you monitor for our credentials on the dark web?
Yes — continuous credential-exposure and dark-web monitoring is part of the capability, feeding directly into SIRI's threat-intelligence monitoring.
What does “identity attack-path testing” actually involve?
Testing, via SIRI Attack, what an attacker could reach starting from a single compromised identity — privilege escalation, lateral movement and cross-system access — rather than just checking whether login controls are configured correctly.
Does this cover cloud and SaaS identity, not just on-premises Active Directory?
Yes — identity across on-premises, cloud (AWS/Azure/GCP IAM) and SaaS systems is in scope, since privileged access increasingly spans all three.
How often should privileged access be reviewed?
Continuously, not just at grant time — access-recertification review on a regular cadence is part of the recommended programme, since permissions accumulate and go stale as roles change.
