The 20 Coolest Web, Application And Email Security Companies Of 2023: The Security 100

From vendors offering developer-friendly code security tools to those protecting websites against cyberattacks, here’s a look at 20 key web, email and application security companies.

Coolest Web, Email And Application Security Companies

Cybersecurity companies focused on blocking cyberattacks via the web, emails and applications remain as pivotal as ever. A report from IBM Security X-Force found that when it comes to the ways that attackers are gaining initial access into a victim’s systems, phishing remains on top, with 41 percent of incidents in 2022 having involved phishing. Coming in second was exploitation of public-facing applications, accounting for 26 percent of incidents last year, according to the X-Force Threat Intelligence Index 2023.

In 17 percent of incidents in 2022, attackers succeeded at deploying ransomware, the report found. What that tells us is that the best way to protect against the onslaught of attempted ransomware attacks is to shut down a phishing attack before it can advance any further, and address application vulnerabilities and misconfigurations that can be exploited.

Without a doubt, tools for web, email and application security have had to evolve to keep up with the attackers. In particular, the rise in headline-making critical vulnerabilities, such as Log4Shell and ProxyShell, is a prime piece of evidence that many organizations need to double down on their application security efforts. Tools for spotting vulnerable code earlier in the software development process, often referred to as “shifting left,” have been one major advancement in the application security sphere. Key vendors aiming to enable this shift include Checkmarx, Contrast Security, Lacework, Snyk and Veracode.

Meanwhile, well-established email security vendors such as Barracuda Networks, Mimecast and Proofpoint have also been enhancing their offerings as attackers have refined their phishing tactics.

And in web security, notable vendors with solutions such as secure web gateway (SWG), web application firewall (WAF) and distributed denial-of-service (DDoS) mitigation include Akamai Technologies, Cloudflare, Imperva, F5, Menlo Security, Netskope and Zscaler.

What follows are the 20 web, email and application security companies that made our Security 100 for 2023.
