What Silent Push does
Silent Push is a Reston, Virginia-based private cybersecurity company that operates a Preemptive Cyber Defense platform built on its proprietary Indicators of Future Attack (IOFA) methodology. The platform continuously scans the entire IPv4 and IPv6 address space, aggregating live and historic DNS data, WHOIS information, certificate data, and web content into behavioral fingerprints that identify adversary infrastructure during reconnaissance and weaponization phases, before attacks are fully deployed. The company targets Security Operations Center managers, incident response teams, and Cyber Threat Intelligence analysts at Fortune 500 enterprises, defense contractors, government agencies, and national security organizations, with reported customer coverage extending to half of the Fortune 30 across retail, banking, and insurance sectors.
The platform is organized into modular offerings: Threat Hunting (unknown-infrastructure discovery), Brand Protection (DNS monitoring and impersonation detection), Automated Intelligence (curated IOFA feeds and APT tracking), and Traffic Origin (geographic attribution piercing VPN/Tor/proxy anonymization). A 100+ endpoint REST API and SPQL query language support integration across SIEM (Splunk, Sumo Logic, Google SecOps), SOAR (Torq, Tines, Palo Alto XSOAR, Swimlane), and TIP (ThreatConnect, OpenCTI, Cyware) ecosystems. In June 2026, the company released Platform 6.0 with restructured navigation (Defend, Insight, Reconnaissance), a hosted MCP Server connecting its data to Claude and ChatGPT, Bulk Enrichment, and a TLP Amber Report API. Revenue is generated through annual enterprise subscriptions, API access, and automated feed intelligence, supplemented by a freemium Community Edition for top-of-funnel adoption. Distribution combines direct enterprise sales, regional channel partners (CDL Cyber Intelligence in the UK, CyberLion in the Nordics, Unfold in AU/NZ), Carahsoft for U.S. government sales, and Tradewinds Solutions Marketplace awardability.
Founded publicly in 2023 with a $10 million seed round led by Ten Eleven Ventures, Silent Push has since raised $10 million Series A (December 2024, co-led by Ten Eleven Ventures and StepStone Group) and $10 million Series B (September 2025, StepStone Group lead) for cumulative funding of approximately $30 million. The company reported $10.3 million ARR at a $30.9 million disclosed valuation as of 2025. In December 2025, Silent Push completed its acquisition of HYAS to expand adversary-infrastructure visibility and global presence. The executive team is led by co-founders Ken Bagnall (CEO) and John Jensen (CTO), with Nicola Walsh as CFO, Brad Arnold as COO, Kirk Appelman as VP of Sales, Thomas Bain as CMO (appointed May 2026), and Michael Sweeney directing the Preemptive Cyber Defense Team.

Silent Push competitors and assessment
Company assessmentDirect peers
- ThreatConnect: Threat intelligence platform with CAL-based analytics and TIP capabilities. Listed as a Silent Push integration partner, indicating tight technical overlap in enterprise CTI workflows.
- Recorded Future: The largest standalone threat intelligence platform, owned by Mastercard. Directly comparable to Silent Push in delivering curated threat feeds, infrastructure tracking, and pre-breach intelligence to enterprise SOC and CTI teams.
- Mandiant: Industry-leading threat intelligence and incident response firm (now part of Google Cloud). Overlaps with Silent Push on adversary infrastructure tracking, APT research, and enterprise/government CTI consumption.
- DomainTools: Pioneer in DNS and WHOIS intelligence for threat hunting and brand protection. Closest direct competitor on the underlying DNS telemetry that powers Silent Push's IOFA feeds.
- Anomali: Threat intelligence platform combining feeds, TIP functionality, and analytics. Competes for the same SOC/CTI buyer with overlapping capability in pivoting across adversary infrastructure indicators.
- HYAS: Adversary infrastructure intelligence platform acquired by Silent Push in December 2025. Historically a direct competitor in infrastructure attribution, now combined into the Silent Push platform.
Emerging players
- Censys: Internet-wide scanning and attack surface management with comparable passive DNS and certificate intelligence. Overlaps with Silent Push on internet-facing infrastructure visibility but emphasizes ASM over preemptive threat intel.
Broad incumbents
- CrowdStrike: Endpoint-led platform with growing threat intelligence unit (Falcon Intelligence). Bundles threat intel into a broader XDR platform, creating competitive pressure on standalone intel vendors.
- Palo Alto Networks (Unit 42): Threat intelligence and incident response arm of one of the largest security platforms. Competes for the same enterprise CTI budget as Silent Push but bundles intel with firewall, XDR, and SIEM.
- Microsoft Defender Threat Intelligence: Microsoft's native threat intelligence offering bundled with Defender and Sentinel. Pressures standalone vendors on price/bundling for enterprise buyers standardized on the Microsoft security stack.
