vCISO & Security Advisory for Toronto and Canadian Technology Teams

Fractional security leadership for roadmaps, customer reviews, vendor assessments, cloud architecture review, and risk direction—as an ongoing program, not a one-off workshop.

Who it’s for

Startups and mid-market technology teams without a full-time CISO; teams facing customer security reviews; teams keeping SOC 2 or ISO 27001 current who need ongoing ownership between audits; Canadian and US product companies that want one partner across vCISO, VAPT, and compliance. Engagements stay tied to the rest of the managed security program.

What a vCISO engagement covers

Engagements cover security roadmap and risk direction, customer security reviews and questionnaires, vendor and third-party risk reviews, cloud architecture review, and coordination of continuous VAPT and year-round compliance workstreams across the CyberImmune program. Work stays coordinated so priorities do not conflict.

Common questions

A virtual or fractional CISO—senior security leadership on a retainer or advisory basis focused on roadmap, risk, and buyer or audit readiness for your team.

When customer security reviews, compliance, or risk decisions outpace founders and engineering leads, but a full-time CISO hire is not yet justified for the company’s stage.

Yes. A vCISO coordinates evidence owners, policies, and vendor reviews alongside CyberImmune’s year-round readiness program described on /soc-2 and /iso-27001.

Yes. We deliver across Canada, the United States, and India from our Toronto headquarters, with the same engagement model for every vCISO advisory client.
