Threater

Threater is a network security vendor that has been through two rebrands in four years: founded in 2012 as Bandura Cyber, it renamed to ThreatBlockr in 2022 after a $5M raise, then rebranded again to Threater in November 2023 as it broadened beyond pure blocking into threat intelligence aggregation and analysis. The core product, now called Threater Enforce (formerly ThreatBlockr Edge), sits on the network and automates a specific, unglamorous but valuable job: taking massive volumes of threat intelligence — malicious IPs, domains, and indicators from multiple feeds — and enforcing them at wire speed across an entire network, without the manual firewall rule maintenance that makes most organizations abandon threat-intel-driven blocking after the first few thousand indicators.

As part of the 2023 rebrand, Threater made its threat intelligence aggregation product free to use and expanded what it calls a cyber threat intelligence marketplace, aiming to become the aggregation and enforcement layer that sits between existing threat feeds and existing firewalls/network infrastructure rather than replacing either. The platform deploys as a physical appliance, virtual appliance, or cloud instance across the major cloud providers.

The company is small (11-50 employees) and has raised roughly $19.4M in venture funding across nine rounds from investors including Grotech Ventures, Cultivation Capital, and the Maryland Venture Fund, most recently a Series A2 round in 2022. It is headquartered in Tysons, Virginia. Threater does not publish independent third-party performance benchmarks (e.g., MITRE ATT&CK evaluation results) for its enforcement claims; its differentiation rests on the scale-of-indicators argument (handling millions of IOCs that overwhelm conventional firewall rule tables) rather than published comparative testing.
