About LinearStack

An enterprise advisory partner built for measurable threat reduction

Founded in 2013 by security practitioners frustrated with tool-first MSSPs, LinearStack was built around a different thesis: enterprise security effectiveness comes from disciplined operations, not from buying more products. Over thirteen years we have evolved from a niche consultancy into an enterprise advisory partner — today a team of 30+ professionals operating from two delivery centers, accountable for quarter-over-quarter threat reduction across distributed organisations.

What we believe

Security effectiveness is engineered, not assumed.

Mission
Reduce enterprise threat exposure measurably — quarter over quarter — through disciplined operations rather than additional tools.

Vision
A world where security effectiveness is engineered, not assumed — where every CISO can answer the question: "Are we safer than last quarter?"

Principles

  • Operations beat tools.
  • Outcomes beat activity.
  • Discipline compounds.
  • Boards deserve clarity.
  • Partnership over transactions.
