Two services. One security intelligence platform.
YellowShielder brings together external attack surface management and vulnerability intelligence — discover what you expose, know which threats can actually hurt you, and turn it all into governed, auditable remediation with full multi-tenant isolation.
One platform, two dedicated security services.
Continuously discover every internet-facing asset, detect exposures and leaked data, and turn findings into governed, repeatable remediation.
- Asset discovery & risk grading
- Exposure & data-leak monitoring
- Prioritised findings & remediation
- Attack graph & compliance mapping
One unified live feed of every CVE disclosure worldwide, ranked by real-world exploitation likelihood — so you know which threats can actually hurt you.
- Unified CVE/KEV feed with deduplication
- Exploitation-first ranking (EPSS)
- Instant PoC & ransomware tracking
- Auto-enriched digests on your schedule
Every module works off one governed source of truth.
Map everything you expose to the internet.
Automated discovery of domains, subdomains, hosts, IPs, ports and cloud footprint — with change-detection and a risk grade that trends over time.
- Continuous asset & subdomain discovery
- Risk grade with historical trend
- Change-detection since last scan
Catch leaked secrets and breached credentials early.
Detect exposed secrets, leaked credentials and dark-web mentions tied to your domains — prioritised by real business risk so your team fixes what matters first.
- Credential-leak & breach monitoring
- Exposed secrets & misconfiguration detection
- CVE / KEV vulnerability scoring
Know which vulnerabilities actually hurt you.
One unified live feed of every CVE disclosure worldwide, merged and de-duplicated. Ranked by exploitation likelihood, not just severity — so your team knows what can actually be weaponised.
- Unified CVE/KEV feed with deduplication
- Exploitation-first ranking (EPSS score, proof-of-concepts)
- Instant PoC lookup and threat activity tracking
- Auto-enriched digests on your schedule
Prove your posture. Map it to the frameworks you answer to.
Board-ready dashboards for the CIO, an append-only audit trail, and control mapping across ISO 27001, NIST CSF, DORA, and GDPR — live evidence from your platform activity.
- Multi-framework control mapping (ISO/NIST/DORA/GDPR)
- Board-ready posture dashboards & executive reports
- Append-only audit trail (100% traceability)
From discovery to governed remediation — on one platform.
Discover
Launch a scan and automatically map every internet-facing asset, subdomain and open service.
Detect
Surface vulnerabilities, leaked data and misconfigurations, each scored by business risk.
Defend
Assign, remediate and prove — with audit trail, reports and framework-mapped compliance.
Built for the SOC, the RSSI and the board — on one source of truth.
Shadow IT, forgotten subdomains and cloud buckets surface automatically — not once a year, but every scan.
Every finding is scored by exploitability and business impact, so the team fixes what actually matters first.
Breached passwords and exposed secrets tied to your domains are flagged before they are abused.
Executive posture dashboards and one-click PDF/CSV/Excel exports for the CIO and audit.
Every list, metric and query is scoped to the tenant. Client A never sees Client B — by design.
Your activity maps live to ISO 27001, NIST CSF, DORA and GDPR controls, with evidence from the audit trail.
Questions, answered.
What is External Attack Surface Management?
EASM continuously discovers and monitors every internet-facing asset your organisation exposes — domains, subdomains, IPs, services, cloud footprint — and surfaces the exposures an attacker could exploit, before they do.
How is tenant data kept separate?
Every target list, exposure metric and query is filtered by the current tenant. Data from one client organisation is never visible from another — enforced consistently across Surface Intelligence, Exposure and every other page.
Which compliance frameworks are supported?
ISO/IEC 27001, NIST CSF 2.0, DORA and GDPR out of the box, with control coverage mapped live to your platform activity and exportable as an evidence report.
How fast can we get value?
Launch a scan and you get a prioritised findings view in minutes — no long onboarding, no agents to deploy on external assets.
