The 20 Coolest Web, Email and Application Security Companies Of 2024: The Security 100

From vendors offering code security tools to those protecting inboxes and websites against attacks, here’s a look at 20 key companies in web, email and application security.

Among the major disclosures in a recent AI security report from Microsoft and OpenAI was this doozy: It’s likely that nation-state hackers are, indeed, using GenAI to create phishing emails. While the potential for GenAI-powered phishing and social engineering has been widely discussed since the debut of OpenAI’s ChatGPT more than a year ago, the report suggests that it’s really happening in the wild.

Notably, according to the report’s findings, attackers from nation-state groups in China, North Korea and Iran are among those taking advantage of Large Language Model (LLM) technology as part of their phishing campaigns. “Our analysis of the current use of LLM technology by threat actors revealed behaviors consistent with attackers using AI as another productivity tool on the offensive landscape,” Microsoft said in the report.

In other words, now bolstered by GenAI, phishing and social engineering tactics may pose an even bigger threat than in the past — and a huge opportunity for email security vendors and their partners to help with protecting organizations of all sizes.

Meanwhile, with vulnerability exploits constituting another big focus area for threat actors in 2024, the adoption of tools for eliminating vulnerabilities during software development remains a growing priority for many organizations. There’s been no subsidence in browser-based threats either, with the continued frequency of attacks such as cross-site scripting — leading to ongoing demand for web application firewalls and other web security tools.
