Silent Push announced a $10 million Series B round in September 2025, naming StepStone Group, Ten Eleven, and Knollwood Investment Advisory as participating investors. The company said the financing brought its total funding to $32 million and would support product innovation, global expansion, and customer momentum. Silent Push sells cybersecurity intelligence software and API access, not a consumer product.
What does Silent Push do?
Silent Push describes itself as a preemptive cybersecurity intelligence company. Its Indicators of Future Attack (IOFA) concept is designed to help security teams identify emerging attacker infrastructure before it is used in an attack. The company offers a platform and API integrations with security tools such as SIEM, XDR, SOAR, TIP, and OSINT systems. It also makes a free Community Edition available. Silent Push product page
The company says its intelligence draws on live and historical DNS, web content scanning, certificate data, and WHOIS information to identify behavioral fingerprints and hidden infrastructure. It lists threat hunting, brand protection against phishing and impersonation, and automated intelligence feeds for security workflows among its use cases. These descriptions are company claims, not independent evaluations of product performance.

What is Indicators of Future Attack?
IOFA is Silent Push’s term for intelligence aimed at finding attacker infrastructure before it is weaponized. That timing distinguishes the company’s stated approach from intelligence centered on indicators of compromise (IOCs), which generally help teams recognize infrastructure or artifacts associated with attacks already observed. Silent Push presents earlier identification as a way to support proactive hunting and security workflows; the materials do not establish that its approach is objectively more effective than IOC-led methods.
In an August 4, 2026 announcement about an API-first offering for cybersecurity companies, Silent Push said its IOFA identifies adversary infrastructure 104 days on average — Silent Push, 2026 (company-reported). The company did not provide an independent verification of that figure in the cited announcement. Silent Push’s August 2026 API announcement
