Your access tool is a vendor with a copy of your infrastructure map

Disclosure: I work on Tessera, which is self-hosted. That is the position I am arguing from, and the costs of that position are in the last section. Security questionnaires ask where customer data is processed. Access-control tools tend to get a shallow answer to that question, because people think of them as gatekeepers rather than as data processors. They are both. Here is what a hosted access…

Your access tool is essentially a vendor that holds a copy of your infrastructure map. Security questionnaires often ask where customer data is processed, but access-control tools tend to receive a cursory answer, as they are perceived as merely gatekeepers rather than data processors. However, they serve both roles. A hosted access broker possesses comprehensive knowledge about your infrastructure, including your infrastructure inventory (such as hostnames, addresses, cluster endpoints, database names, and environment labels), your organizational structure (including access rights and approval processes), session content (such as commands, queries, and output), and timing (such as incident occurrences and escalation procedures).

This information is crucial for an attacker, as it provides a detailed map of your estate, enabling them to determine where to focus their efforts.

What running your own SSH certificate authority actually costs

Disclosure: I work on Tessera, which is on the buy side of this. I have tried to cost the build side properly, because a comparison where the build option looks stupid is a comparison nobody believes.

  • Initial build takes about a week, including key generation and configuration.
  • Securing CA key adds 2-4 weeks of operational work due to HSM/KMS integration.
  • Ongoing maintenance costs around $15k–$50k annually, totaling $75k–$150k for build and upkeep.

Four security decisions that look like nothing and are not

Disclosure: these are decisions from Tessera, which I work on. They are all small enough to copy into your own service, which is why they are worth writing up.

  • Count against real TCP connection address, not X-Forwarded-For header
  • Validate target addresses to prevent Server-Side Request Forgery
  • Store SSH host keys on first use, reject changed keys later

Auditors do not want your policy. They want an artefact.

Disclosure: I work on an access tool (Tessera), mentioned once at the end. Everything before that is about evidence, and applies whatever you use.

  • Audits fail due to lack of evidence, not missing controls
  • Organizations need specific artifacts to satisfy auditors
  • Artifact properties: separate storage, immutability, exportability

Privileged access management skipped everyone between 50 and 500 engineers

Disclosure: I work on Tessera, which is one of the tools in the gap I am describing. Ask a fifty-person engineering organisation how they control production access and you will hear the same answer…

  • Privileged access management tools become unaffordable for mid-sized organizations
  • Self-hosting and per-seat pricing make PAM viable for 50-500 engineer firms
  • Tessera, Teleport, and Boundary offer free tiers with required features
