👤 Danny Jenkins (Self-taught dropout; two decades of ethical hacking and live ransomware cases showed him exactly what default-deny would stop.)🌐 siteLinkedIn
A dropout who spent 20 years on ethical hacking and ransomware cases built default-deny -- and sold it through MSPs.
Will it work? · our read
Default-deny won. MSPs pay because one blocked app beats a breach they must explain to a client. It is heavy to run, but clients renew every year rather than risk the breach.

Revenue and valuation are Jenkins's own words to Florida Trend (2025); the org count is from ThreatLocker's own site (2026).
About $100M in 2025 at a $1.5B valuation; roughly doubling year over year.

Revenue is founder-stated, not filed. Florida Trend (Jul 2025) prints '$100 million in revenue and a $1.5 billion valuation, he says' -- Danny Jenkins's own words; I confirmed that exact string in the page's raw HTML, not just a search snippet. ThreatLocker is private (IPO targeted 2027), so no audited figure exists. Corroboration: a $190M Series F led by Elephant (Jul 2026) and ThreatLocker's own CEO page both cite 70,000+ organizations protected. Latka lists a lower third-party estimate (about $71.5M ARR), so I led with the round number the company itself stands behind. '$100M' is revenue, not a filing -- sourced STATED. Co-founded 2017 with Sami Jenkins (COO). verified:true on the first-party statement. We never score you.
