đź“° In the News: A Tale of Two Existential Vectors
We begin this edition with two major security signals that highlight the twin challenges of macro geopolitical shifts and micro architectural failure.
1. Hostile States and the Boardroom Realignment
The head of the UK’s National Cyber Security Centre (NCSC), Dr Richard Horne, delivered a sobering warning at the RUSI Annual Security Lecture. Of the 200-plus cyber incidents affecting UK critical national infrastructure in the year to May 2026, roughly three-quarters were linked directly to hostile states—with China, Russia, and Iran explicitly named. The NCSC is currently managing around four nationally significant incidents every single week.
The Secure Velocity Take: For enterprise leaders, the takeaway isn't about panicking over any single geopolitical actor. It is about structural resilience. Dr Horne noted that cybersecurity cannot be treated simply as a "risk to be managed" on a static register, but as an ongoing contest. To survive, we have to stop talking to boards in dense, technical jargon and start describing these risks in concrete, business-resilience terms. If disruption is an adversary's goal, how fast can you restore core business operations?
2. Stolen Tokens: The Klue Supply-Chain Breach
While the NCSC warns of macro state-level contests, a textbook supply chain breach illustrated exactly how adversaries gain initial footholds. In mid-June 2026, competitive-intelligence SaaS platform Klue confirmed a massive downstream compromise.
Attackers did not use complex malware or zero-day exploits. Instead, they compromised a single legacy machine credential—a disused service account built for a prototype that was never decommissioned. From there, they harvested long-lived OAuth tokens used by Klue's integration infrastructure to connect to downstream customers’ environments. The result? Attackers lateralised access into nearly 200 customer environments—including Salesforce databases belonging to multiple prominent security firms.
The Secure Velocity Take: This is a perfect example of what happens when machine identity is left in a governance black hole. The focus of modern identity programmes has traditionally been on human users (passwords, MFA), but the true back door is often an unmonitored Non-Human Identity (NHI) holding standing OAuth access.
Shift-Left Governance: Machine vs. Human Identities
As organisations migrate and modernise their workloads across various cloud environments, the explosive proliferation of Non-Human Identities (NHIs)—such as service accounts, API keys, OAuth tokens, and secrets—far outpaces human identity creation. In a typical cloud ecosystem, machine identities routinely outnumber human users by at least 10 to 1.
Yet, our governance practices remain heavily lopsided. We spend immense energy ensuring a human developer uses biometric multi-factor authentication, while a forgotten, highly privileged prototype API token lies dormant in a configuration file for years.
The Klue breach demonstrates that an identity programme is fundamentally incomplete if it doesn't treat automated machine credentials with the exact same lifecycle rigour applied to employee onboarding and offboarding.
Designing Paved Roads for Non-Human Identities
To implement a cloud modernization strategy with a true security twist, your governance model must actively eliminate stale machine privileges without slowing down automated engineering pipelines. This requires three core architectural standards:
1. Eliminate Long-Lived API Keys and Permanent Tokens
If your cloud-native integrations rely on static, long-lived client secrets, you are sitting on a time bomb. If a prototype or testing service account is spun up, it must have a strict, automated Time-to-Live (TTL) expiration built directly into its definition.
- The Standard: Move towards temporary, dynamic secret generation. Rely on short-lived tokens and machine identity federation (such as OIDC-based authentication) wherever possible. If an automated process finishes its run, its identity credentials should automatically expire and become completely useless to an attacker.
2. Enforce Non-Human Identity Inventory and Decommissioning
Most organisations have an automated pipeline for offboarding an employee when they leave the firm, but what happens when a software prototype is abandoned?
- The Standard: Just as you maintain a registry of human employees, you must enforce a strict lifecycle for NHIs. If a machine identity or third-party OAuth token shows zero API traffic for more than 30 days, an automated policy should quarantine that identity and notify the engineering owners for immediate decommissioning.
3. Translate Infrastructure Security into Business Resilience
Tying this back to the NCSC's guidance: your board does not need to understand the technical nuances of OAuth token harvesting or service account configurations. They need to understand blast radius and operational impact.
- The Standard: Frame your machine identity governance in business terms: "By eliminating static third-party integration tokens and enforcing automated session expiration, we have reduced the potential blast radius of a partner breach by 85% and guaranteed continuous business operations." That is how you turn a technical security task into a board-level resilience victory.
The Third-Party OAuth Explosion
The Klue compromise highlights the fundamental flaw in modern third-party risk management. The vulnerability was not in the core application; it was in the trusted connective tissue between separate platforms. When you authorise a SaaS provider or plug-in to read and write to your enterprise systems, you inherit their entire security posture.
If your risk assessment team is still relying on static vendor questionnaires, they cannot tell you if a vendor's engineer left a legacy prototype credential open in their testing environment. Static paper compliance will never reveal active credential drift or unrotated machine secrets.
Seeking Beta Partners: Vendor Assure
We built Vendor Assure specifically to give enterprises real-time, continuous visibility into their external supply chain and third-party risk posture. It moves beyond the limitations of point-in-time security questionnaires, automating the discovery of vulnerabilities and risk profiles across your ecosystem.
Vendor Assure helps you bridge the exact gap highlighted by the NCSC and the Klue breach: it continuously monitors your third-party risks, giving you the real-time visibility you need to protect your cloud perimeter and describe systemic risk to your board in clear business metrics.
We are currently looking for three forward-thinking enterprise teams executing cloud transformations to join our Beta programme. If you are ready to eliminate manual vendor blind spots and bring continuous assurance to your digital supply chain, let's connect for a brief, no-pitch conversation.
