“We can’t protect what we don’t know about.” This often-repeated truth hits home for CISOs when it comes to digital certificates, encryption keys, and machine identities. Many breaches or outages trace back to an unknown, forgotten, or unmanaged certificate or cryptographic asset lurking somewhere in a complex IT estate. That’s why the first stage of the Trust Control Plane is Continuous Discovery and Visibility – establishing a single source of truth for every digital identity and cryptographic asset in your organization.
The Challenge: “We Don’t Know What We Have”
In practice, achieving enterprise-wide visibility of machine identities and cryptography is easier said than done. Most large organizations still struggle with significant blind spots:
- Silos and Shadow Systems: Certificates and keys live in myriad places – data centers, cloud platforms, DevOps tools, IoT devices, applications. Different teams may deploy their own certificate authorities or rely on default (and often unmanaged) credentials. One global bank admitted, “We don’t even know what we have, and even when we do, we don’t always know who owns it”. This fragmentation leaves security teams in the dark.
- Manual Inventory = Moving Target: Traditional approaches to inventory (spreadsheets, occasional scans) cannot keep up with the dynamic nature of modern IT. Cloud instances spin up and down, containers and AI microservices appear autonomously – each potentially introducing new certificates or keys. A one-time audit might find thousands of identities, but the next week the landscape has already changed.
- Risk of Unknowns: The cost of blind spots is steep. A recent industry survey found only 17% of organizations have full real-time visibility into all their certificates. 86% suffered at least one outage in the past year due to expired or mismanaged certificates – outages that not only disrupt operations but can erode customer trust and revenue. Unseen certificates = unmitigated risk.
In short, without complete, continuous visibility, proactive trust control is impossible. You cannot secure or manage what you haven’t discovered. Discovery is the foundation on which all later stages – from policy enforcement to automation – are built. Skipping it is a recipe for reactive firefighting and compliance failures down the road.
From Visibility to Observability: Seeing and Understanding
Leading organizations are expanding “discovery” into true observability – a richer, context-aware view that not only finds every identity and certificate but also illuminates its usage and environment. This shift is vital for turning raw inventory data into security insight. Continuous discovery must answer not just “what is this certificate or cryptographic asset?” but also “where is it, how is it configured, and what happens if there’s an issue?”:
- Continuous, Not One-Time: The Trust Control Plane uses always-on discovery tooling (active network scanning, agent-based discovery in hosts and cloud, API integrations, etc.) to maintain an up-to-date system-of-record of all machine identities and cryptographic assets. When new instances or cryptographic assets appear, they are automatically inventoried and assessed. This real-time approach closes the gap that one-off scanning leaves open.
- Context and Ownership: Modern discovery isn’t just about a list of assets – it’s about understanding context. By gathering metadata (e.g. host name, device type, application owner, issuance source, expiration date, associated services), the Trust Control Plane builds a rich cryptographic “asset profile” for each item. This helps answer “Is this certificate critical? Who is responsible? What system would break if it expired?” – exactly the questions a CISO or IT risk manager needs to know to prioritize and respond.
- Beyond Certificates – Full Crypto Posture: A key differentiator of a mature trust program is that discovery extends beyond just TLS certificates. You need visibility into the broader cryptographic posture: code signing keys, SSH keys, secrets, algorithm versions and library versions (e.g. detection of outdated cryptographic libraries), HSM and key vault inventories, etc. This comprehensive view is crucial in the era of post-quantum cryptography – you can’t migrate to safer algorithms if you don’t know where vulnerable ones are used. The trust control approach casts the widest possible net to see all these artifacts in one place.
By evolving raw discovery into intelligent observability, you gain “x-ray vision” into your trust environment. For example, one Keyfactor customer combined network scanning and endpoint discovery to find hundreds of previously unknown certificates and contextualize them by owner and business criticality. With that insight, they could eliminate redundant or risky certificates (reducing their attack surface) and align stakeholders to each asset (ensuring someone is accountable for renewal). Visibility isn’t just about inventory – it’s about creating actionable intelligence.
Business Outcomes: Risk Reduction and Readiness
So what does Stage 1: Observability – Continuous Discovery & Visibility ultimately deliver for a CISO or security executive?
- Proactive Risk Reduction: By eliminating blind spots, you pre-empt incidents. Unknown certificates and rogue keys are often the root of breaches and downtime. Continuous discovery lets you find and remediate issues before they cause harm – whether it’s an expired certificate that would have caused an outage, or a weak cryptographic algorithm that would have opened a vulnerability.
- Stronger Compliance & Trust Confidence: Regulators and customers increasingly demand proof that organizations have full control of their keys and certificates. An always-updated inventory serves as hard evidence of governance. It also boosts confidence internally – IT leadership can see that digital trust assets are under control (no more “fingers crossed” approach during audits).
- Foundation for Automation: Automation and policy enforcement rely on knowing where to apply controls. Continuous discovery provides that roadmap. It lays the groundwork for orchestrating renewals and enforcing standards enterprise-wide. In fact, many automation initiatives stall due to incomplete data – the trust control model ensures automation has accurate input to work from.
One Gartner report calls out “comprehensive discovery and audit of every account and credential” as the first practical step in tackling machine identity challenges. Without it, efforts in later stages (like adding new security controls or responding to threats) will be fundamentally limited. The Trust Control Plane makes this step an integral, continuous part of day-to-day operations – not an occasional project.
In the next part of this series (Stage 2: Analyze & Measure, we’ll examine how to leverage that complete visibility to define rules and issue identities at scale, ensuring that every machine identity in your inventory is not only known, but also trusted and governed.
