About

FirewallSync is an independent publication of practical cybersecurity writing for the engineers who have to implement security, not just audit it.

FirewallSync covers the parts of cybersecurity that change how engineering teams work day to day: access control, application and API security, cloud identity, incident response, and the new risks that come with AI agents and LLM applications. We write for the people who have to implement security, not just the people auditing it.

What we cover

How we write

Every article starts with the problem a team actually runs into, then gives a concrete fix: a rollout order, a checklist, a comparison. We prefer field-tested advice over vendor feature lists, and we say when a recommendation depends on your team’s size or risk tolerance. The details are in our editorial policy.

Who writes it

Articles carry the name of their writer. Our writers:

Craig Leslie

Researcher and writer

Craig Leslie researches and writes about identity, security operations and AI security for FirewallSync. He checks each technical claim against its original source and says when advice depends on a team's size or risk tolerance.

John Marshall

Researcher and writer

John Marshall researches and writes about application, API and cloud security for FirewallSync. He works from standards, vendor documentation and government advisories, and lists his sources at the end of every article.

Pieces without a named writer appear under FirewallSync Editorial. We also publish guest contributions from practitioners; see Write for Us.

Money and independence

Sponsored content, if we publish any, is labeled clearly at the top of the article. See our advertising page and editorial policy.
