Zafran Security, which develops technology to help organisations automate exposure management, has secured fresh backing from investors as demand for intelligent defence tools accelerates.
The firm has raised $60m in a Series C investment round led by Menlo Ventures. Existing backers Sequoia Capital and Cyberstarts took part, along with PSP Growth, Vintage Investment Partners, and Knollwood Investment. This latest injection takes Zafran’s total funding to $130m.
Zafran specialises in threat exposure management powered by agentic artificial intelligence. Its technology supports large enterprises in mapping assets, detecting vulnerabilities, analysing risk and orchestrating remediation workflows autonomously.
According to the company, the new funding will be used to accelerate product innovation and support international expansion. Zafran is positioning its platform as a way for security teams to move faster in mitigating critical weaknesses before they are exploited.
Investor appetite reflects the growing urgency around cyber risk. Zafran said it has more than doubled its valuation since its last funding round and has tripled its annual recurring revenue, buoyed by demand from sectors such as healthcare, financial services, manufacturing and technology. Its customer base now includes multiple Fortune 500 companies, which are using its platform to cut remediation times from weeks to hours.
The firm argues that rising AI-powered attack automation has increased the speed at which vulnerabilities are exploited. It reported that in the first quarter of 2025, 30% of known exploited vulnerabilities were weaponised within a day of disclosure, leaving traditional security processes struggling to keep pace.
Zafran Security CEO and co-founder Sanaz Yashar said, “We must not allow attackers to claim the AI advantage. This investment propels our AI innovation forward, building a new model for exposure management through autonomous agents that empowers defenders to fight back.”
Zafran used the announcement to unveil Agentic Exposure Management, an end-to-end capability underpinned by its AI-native Exposure Graph. This uses autonomous agents to identify and assess risk, map controls, and carry out automated fixes guided by human oversight.
Menlo Ventures partner Rama Sekhar added, “Vulnerability management burns massive analyst hours on repetitive triage and manual patching, the kind of service-oriented work that AI agents excel at automating”, adding that Zafran’s platform “is what AI-native security looks like.”
Steve Lodin, vice president of infosec at Sallie Mae, said, “In seconds, agentic AI can reveal what teams previously only suspected: the biggest risks to the business, why they matter, and which actions will truly move the needle.”
