Silent Push secures $10M in Series B funding

Silent Push, a cybersecurity startup focused on preemptive defense, has secured $10 million in Series B funding to accelerate product innovation, expand internationally, and strengthen customer adoption, according to SiliconANGLE.

Founded in 2020 by former FireEye executives Ken Bagnall and John Jensen, the company specializes in detecting "Indicators of Future Attack," signals such as DNS infrastructure changes, certificate use, and WHOIS data that help security teams spot adversary infrastructure before it is weaponized. Its scanning and aggregation platform monitors global IPv4 and IPv6 activity, live DNS, and web content to map attacker tactics and identify early-stage campaigns.

According to the company, this approach allows organizations to block attacks in advance, protect brands from phishing or spoofing, and monitor their own external attack surfaces for misconfigurations. CEO Bagnall emphasized Silent Push's goal of equipping every organization with timely intelligence.

The round, led by StepStone Group with Ten Eleven and Knollwood Investment Advisory, brings the company's total funding to $32 million.
