TL;DR: Attackers are increasingly subverting firewalls, VPNs, secure gateways, and third-party integrations to gain trusted access and move laterally inside enterprise networks, according to ColorTokens. The security lesson is that containment, not perimeter confidence, is now the decisive control variable when the edge itself becomes an attack path.

By the numbers:
- As of early 2025, 85% of organisations lack full visibility into third-party vendors connected via OAuth apps.
Questions worth separating out
Q: What breaks when perimeter devices are not monitored like attackable assets?
A: The main failure is that defenders lose visibility at the exact point attackers are trying to compress exploit timelines.
Q: Why do edge technologies create outsized lateral movement risk?
A: Edge technologies are often granted broad administrative and network privileges so they can inspect, route, and enforce policy at scale.
Q: What do security teams get wrong about microsegmentation?
A: They often treat it as a one-time network redesign instead of an iterative control that depends on current workload behaviour.
Practitioner guidance
- Classify edge devices as privileged identities Build an inventory of firewalls, VPNs, secure gateways, load balancers, and their admin accounts, then assign ownership, access scope, and review cadence just as you would for other high-risk identities.
- Restrict management-plane reachability Limit admin interfaces to hardened jump paths, dedicated zones, and authenticated operators only.
- Segment for blast-radius reduction Map east-west trust paths from each edge technology and block direct access to crown-jewel systems.

ColorTokens' full article covers the operational detail this post intentionally leaves for the source:
- Examples of recent perimeter technology compromises and how they shifted attacker focus toward trust abuse
- Specific recommendations for verifying rights, credentials, and authorities granted to edge devices
- The article’s breach readiness and impact assessment angle for teams that need a concrete response plan
- Its argument for microsegmentation as the architecture that limits internal spread after compromise

The perimeter is now an identity problem as much as a network problem. When a firewall, gateway, or load balancer can be subverted, the issue is not only packet control but the privileged trust attached to the device and its management plane. That trust must be governed like any other high-risk identity. Practitioners should treat edge systems as privileged actors whose credentials, session rights, and delegated access require continuous scrutiny.
A question worth separating out:
Q: Who is accountable when a trusted integration becomes an attack path?
A: Accountability should sit with both the system owner and the team that approved delegated access. Any integration that can change configuration, export data, or authenticate management actions needs lifecycle ownership, periodic review, and explicit offboarding. If no one owns revocation, the trust boundary is already weak.
