You may need managed security when

  • Security tooling is in place but nobody is watching it outside business hours.
  • Alerts arrive but there is no agreed path from alert to decision to action.
  • Endpoints, sites, or vendors have grown faster than the controls covering them.
  • An incident would depend on improvisation rather than a rehearsed response.
  • Leadership needs evidence that monitoring is actually operating, not merely licensed.

What JLS operates

  • Continuous threat monitoring. Coverage across facilities and endpoints, not a point-in-time scan.
  • Endpoint detection and response. Modern EDR deployed and maintained, with a defined escalation path.
  • Vulnerability and perimeter management. Exposure closed and tracked over time rather than rediscovered each audit.
  • Incident response readiness. A response plan that has been exercised with the people who would have to run it.
  • Reporting leadership can act on. What is being watched, what changed, and what needs a decision.

How this works with a Fractional CISO

These are two different jobs, and JLS provides both.

  • The Fractional CISO owns direction — governance, risk decisions, priorities, and accountability to the board.
  • Managed security delivers operations — the monitoring, detection, and response that runs every day.
  • They can be engaged separately or together. Engaged together, the same organisation is accountable for both the decision and the execution.

If you already have a managed provider, JLS can supply the leadership layer alongside them instead.

Common questions

Do you replace our existing provider?

Not necessarily. JLS can operate the service, or provide independent leadership and coordination alongside internal teams, technology providers, or an existing managed service.

Is this the same as the Fractional CISO service?

No, and that distinction matters. The CISO role owns direction and accountability; managed security delivers day-to-day operations. JLS provides either or both.

What does JLS bring to this?

JLS has been named to MSSP Alert’s Top 250 MSSPs list, most recently ranked #53 in 2025, and previously in 2023, 2020, and the Top 100 in 2018.
