Continuous visibility
Discover certificates everywhere
Build and maintain one continuously updated certificate inventory across
internet-facing and private infrastructure—without manually entering
certificate dates.

01 External certificate discovery
See the certificate presented by every enrolled public service
Register authorised FQDN or IP endpoints and CertAssura inspects the
certificate presented by each TLS service. Periodic reassessment keeps
the inventory aligned with certificate changes and approaching expiry;
it is scoped discovery, not unrestricted Internet-wide scanning.

02 Internal certificate discovery
Bring private infrastructure into the same operating view
Deploy the CertAssura Discovery Agent inside the customer environment
to inspect authorised internal TLS endpoints locally. The agent
reports certificate inventory and health information to the
organisation's CertAssura tenant over outbound HTTPS.
Discovery AgentWindowsLinux
Private-network security model
Local discovery. Customer-controlled scope. Outbound-only reporting.
Internal management interfaces stay private. CertAssura does not need
an inbound route into the customer network, and separate agents can
serve distinct locations or segmented security zones.
- Windows and Linux deployment
- Customer-authorised FQDNs, IPs, ranges and ports
- Local TLS inspection inside the private network
- Outbound HTTPS connectivity to CertAssura
- No inbound connection into the customer network
- Multiple agents for separate sites, networks and security zones
End-to-end control
The complete certificate lifecycle
Move from continuous visibility to owned action in a repeatable
operating model, with policy, approval and audit evidence around every
management transition.

Beyond the public web
Discover certificates where TLS actually lives
Standards-based TLS inspection provides visibility across web servers,
gateways, appliances, cloud and application environments. Discovery does
not depend on a vendor-specific API simply to observe the certificate
presented by an authorised endpoint.

Policy and accountability
Govern certificates as critical digital assets
Translate certificate standards into clear, enforceable policy and keep
ownership visible from initial request through revocation.
✓ Approved issuers
✓ Allowed algorithms
✓ Minimum key strength
✓ Certificate lifetime
✓ Wildcard restrictions
✓ Named ownership
✓ Environment classification
✓ Approval workflows
Digital trust at enterprise scale
Ready for an evolving trust landscape
Use one governance foundation as certificate lifetimes shorten, machine
identities expand and cryptographic requirements change.
Machine identity
Govern certificates as machine identities become more numerous, dynamic and business-critical.
mTLS
Apply lifecycle discipline to mutual-authentication certificates across services and environments.
Code signing
Extend ownership, policy and audit principles to software-signing trust.
S/MIME
Support governed certificate use for trusted email identity and encryption.
Crypto-agility
Maintain the inventory and policy context needed to respond to algorithm, lifetime and post-quantum change.
