Sublime Security Highlighted in 2026 Cyber 150 Growth Ranking

A LinkedIn post from Sublime Security reports that industry analyst Richard Stiennon’s 2026 Cyber 150 list includes the company among what he identifies as the fastest-growing cybersecurity firms. The post notes that Sublime is the only email security vendor featured and describes it as the fastest-growing repeat entrant on the list.

According to the post, the Cyber 150 ranking is derived from IT-Harvest Dashboard data, which tracks thousands of security vendors using signals such as employee growth and market traction. While the methodology is not fully detailed, the recognition suggests that Sublime may be gaining share within the email security niche, potentially enhancing its visibility with customers and investors.

For investors, the emphasis on employee expansion and measured traction may indicate a period of accelerated scaling, with implications for both revenue growth and operating expenses. Inclusion in a third-party growth list could also support Sublime’s positioning against larger incumbents in email security, possibly improving its competitiveness in enterprise sales cycles and partnership discussions.
