We are at the very beginning of a complete transformation of the cybersecurity industry. Today it is possible to publish a book that describes over 300 vendors that were either born in the age of AI or pivoted soon after the advent of ChatGPT. Soon, AI will have penetrated every segment and every vendor. It will become very hard to discern the AI-first vendors.
Because of the rapid change to the industry there are many startups that have taken unique approaches or picked unique problems to which AI can be applied. In this chapter we explore the vendors that do not fit neatly into categories like Governance, Guardrails, or SOC Automation.
There are vendors that address MCP Security, the AI equivalent of APIs. These include Arcade and Golf. Or vendors that are countering phishing with the assistance of AI. You can do this manually if you want to experience the power of AI for countering phishing attacks. Grab the full headers of a suspicious email and upload them to ChatGPT 5.3 and ask for an analysis. It immediately provides a verdict based on DMARC, SPF, sender matching, and content of the email.
There are companies like Clover Security that assists with security during the design phase of a new application. Or Paris-based SafeBrain.ai that helps companies deploy AI safely. Or Terracotta AI which applies behavioral analysis across networked systems, using unsupervised machine learning, to identify zero-day exploits and advanced malware variants without depending on signature libraries or manual rule creation.
Here are all of the vendors providing unique solutions to pressing cybersecurity problems outside the major categories.
