TL;DR: Attackers can now develop an exploit for a known vulnerability in 0.5 days, or 12 hours, and then map networks, compromise identities, and move laterally within minutes, according to ColorTokens. The core change is not faster patching but survivability through enforcement, containment, and minimum-viable operations.

By the numbers:
- At the time of writing this blog in May 2026, the time required for attackers to develop an exploit for a known vulnerability has shrunk from 125 days in 2025 to just 0.5 days, or 12 hours, as of April 2026.
- 64% of valid secrets leaked in 2022 are still valid and exploitable today, proving that detection alone is not enough without automated revocation.
Questions worth separating out
Q: How should security teams implement microsegmentation in environments with compromised identities?
A: They should define the systems that must remain operational, then allow only the communications those systems truly need.
Q: Why do standing privileges create more risk in AI-accelerated attack scenarios?
A: Standing privileges give attackers a persistent path to move once they obtain a credential or token.
Q: What breaks when organisations rely on detection without enforcement?
A: Detection without enforcement leaves attackers free to act after they are seen.
Practitioner guidance
- Map identity paths to business survival zones Identify which user, workload, service account, and recovery identities can reach the systems that define your minimum viable digital enterprise.
- Test whether segmentation actually blocks lateral movement Run controlled scenarios that simulate a compromised identity moving across cloud and internal networks.
- Tie PAM and NHI governance to enclave design Review privileged human access, service accounts, and tokens together so that all high-risk identities are placed within the zones that matter most.

ColorTokens' full blog post covers the operational detail this post intentionally leaves for the source:
- How its breach-ready zoning model maps zones, microsegments, and conduits to material impact.
- Examples of integrating microsegmentation with EDR tools such as CrowdStrike, Microsoft Defender, and SentinelOne.
- The article's practical breakdown of MAMI and MVDE planning for boards and CISOs.
- How deception and denial controls fit into a layered containment strategy.

Microsegmentation is becoming an identity governance control, not just a network control. Once attackers can compromise identities and move laterally in minutes, segmentation determines whether a stolen credential becomes a contained event or an enterprise-wide incident. That is why IAM, PAM, and NHI governance must be designed with traffic enforcement in mind. Practitioners should treat containment as part of access governance, not as a separate network exercise.
A question worth separating out:
Q: Who is accountable for breach-ready zoning and survivability planning?
A: Accountability should sit with both security leadership and business leadership because survivability defines which operations must continue during attack conditions. Boards must help define acceptable material impact, while CISOs and architects translate that into zones, identity boundaries, and containment rules. The governance question is operational continuity, not only technical segmentation.
