ARPSyndicate

ARPSyndicate (also styled A.R.P. Syndicate) is an Indian cyber intelligence company that builds and operates internet-scale intelligence datasets and security products. Rather than reselling third-party feeds, the company runs its own discovery infrastructure and publishes results through APIs that are free to query and priced flatly at scale. Its product portfolio spans data intelligence, enterprise and national security, consumer and executive security, and offensive security services. On the data intelligence side, ARPSyndicate offers Subdomain Center, a shadow IT and subdomain intelligence database that maps hosts across more than a billion registered domains. Its discovery method combines web-scale crawling, real-time Certificate Transparency ingestion and embedding-based host correlation, which the company says surfaces infrastructure that wordlists and certificate logs alone do not reach, including hosts behind reverse proxies. The dataset is integrated into tools such as BBOT, theHarvester and OWASP Amass. Exploit Observer is a vulnerability and exploit intelligence database that resolves identifier sprawl around vulnerabilities. Both are available via freemium APIs, priced at $100/month and $200/month respectively. For enterprise and national security, ARPSyndicate provides Kenzer, a vulnerability management and risk scoring platform covering TPRM, EASM and CTEM, starting from $5k/year, and Osprey Vision, which performs face and object clustering for CCTV and drone feeds, also from $5k/year. Consumer and executive security offerings include EncryptLayer, an Android anti-stalkware, spyware and banking-trojan firewall that is free for consumers, and Digital Executive Protection starting from $1k/yr. The company also delivers offensive security services, including red teaming, VAPT and adversarial simulation, run by the same team that builds its intelligence products, on an engagement basis. ARPSyndicate is headquartered in India and operates globally, serving enterprises, national security organizations, executives and consumers. It is a private company. Its positioning emphasizes proprietary discovery infrastructure, flat-rate API pricing and integration with widely used open-source security tooling.

ARPSyndicate is an Indian cyber intelligence company. Public information about its founding and early history is limited; the company is documented as an Indian cyber intelligence firm and operates a public product platform at arpsyndicate.io. The company's approach is to build and operate its own internet-scale intelligence datasets rather than reselling another vendor's feed. It runs discovery infrastructure and publishes results through APIs that are free to query and priced flatly when used at scale. This model underpins its data intelligence products, Subdomain Center and Exploit Observer. Subdomain Center maps hosts across more than a billion registered domains. Its discovery does not rely on DNS brute force; instead it combines web-scale crawling, real-time Certificate Transparency ingestion and embedding-based host correlation. According to the company, this surfaces infrastructure that wordlists and certificate logs alone do not reach, including hosts sitting behind a reverse proxy. In an independent benchmark cited by the company, it returned more than twice as many valid subdomains as the next-best free source. The dataset has been integrated into BBOT, theHarvester and OWASP Amass. Exploit Observer addresses identifier sprawl around vulnerabilities, where a single real-world flaw typically accumulates multiple identifiers. It is offered as a vulnerability and exploit intelligence database via a freemium API. Beyond data intelligence, ARPSyndicate has expanded into enterprise and national security platforms. Kenzer is a vulnerability management and risk scoring platform covering third-party risk management (TPRM), external attack surface management (EASM) and continuous threat exposure management (CTEM). Osprey Vision performs face and object clustering for CCTV and drone feeds. For consumers and executives, the company offers EncryptLayer, an Android anti-stalkerware, spyware and banking-trojan firewall that is free for consumers, and a Digital Executive Protection service. It also provides offensive security services including red teaming, VAPT and adversarial simulation, delivered by the same team that builds its intelligence products. The company is headquartered in India and operates globally. It is a private company. Its product lineup is priced with freemium APIs for data intelligence, annual enterprise pricing for platforms such as Kenzer and Osprey Vision, and engagement-based pricing for offensive security services.
