The 20 Coolest Web, Email and Application Security Companies Of 2026: The Security 100

From AI-powered vendors protecting email inboxes and web browsers, to providers of modern code security, here’s a look at 20 key companies in web, email and application security.

While the emergence of new AI capabilities has been driving a surge in phishing and social engineering threats for several years now, the arrival of AI agents is expected to increase attacks exponentially. Unlike companies that must go through various processes to adopt agentic tools, attackers “don’t have to deal with corporate politics,” said Bryan Sacks, field CISO at New York-based Myriad360, No. 110 on CRN’s 2025 Solution Provider 500. “They’re just like, ‘All right, I have this tool now. I’m going to use it.’”

The possibility of a further intensification in AI-powered attacks means that organizations—and the solution and service providers who serve them—will be wise to double down on ensuring that they have the security fundamentals addressed, according to cyber defense experts. Modern email and web security is a must-have given the massive boost to phishing and social engineering attacks that AI has enabled.

At the same time, the rise of AI-powered coding tools has led to a spike in software vulnerabilities, meaning that advanced application security is more essential than ever. LLMs are also adept at finding flaws in code and developing exploits, meaning that proactively addressing vulnerabilities will be increasingly pivotal going forward.

For the 2026 Security 100 list, CRN is recognizing 20 web, email and application vendors that have stood out over the past year through delivering a combination of technical advancements and expanded opportunities for solution and service provider partners.

What follows are the 20 web, email and application companies that made the Security 100 list for 2026.
