About DefenseArk (OpenAVN)

DefenseArk, operating under the product brand OpenAVN, is a New York-headquartered cybersecurity company that provides antivirus and threat protection solutions for end-user devices. The company operates a globally distributed network of digital threat detectors that collect and process threat intelligence data, enabling it to identify and deploy defenses against novel malware threats within three to five days of detection — compared to the industry average of up to one month. OpenAVN's product suite includes BrightScan, a lightweight file scanning engine capable of processing up to 35,000 files per second using less than 32 MB of RAM, leveraging Advanced Vector Extensions (AVX) to optimize performance relative to available system resources. A second product, Torus, is a browser extension that functions similarly to a firewall, blocking malicious or suspicious file downloads originating from emails, advertisements, or compromised links during web browsing sessions. The company's underlying technology combines blockchain/distributed ledger technology (DLT) to verify and confirm malware threats across its network, with a crowdsourced model that aggregates threat intelligence from a global base of detectors. This approach is designed to provide faster, more current threat detection compared to traditional static data lakes. OpenAVN targets individual subscribers and device users, positioning its products as consumer and small-scale endpoint security solutions. The company employs a globally distributed workforce and markets its services on a subscription basis.
