About BlackCloak

BlackCloak protects the personal digital lives of executives with cybersecurity, concierge support and incident response. BlackCloak says executives and their families are targets at home, where corporate security cannot reach.[1][2][6]

The Digital Executive Protection Platform delivers against four pillars of protection: Privacy & Identity Defense, AI Threat Protection, Executive Threat Intelligence, and Personal Security Operations. The platform is powered by a Threat Intelligence Engine that continuously gathers insights from open, deep, and dark web sources. BlackCloak provides aggregated, anonymized insights to the customer team to track progress and measure risk reduction.[1][2]

BlackCloak finds, removes, and hides executives' exposed personal data from broker sites, and monitors for breaches across open, deep, and dark web sources. BlackCloak offers data broker removal to minimize publicly available personal data. BlackCloak detects data exposure using known executive data such as email, addresses and names. BlackCloak automates takedown and opt-out requests. Executives can track progress through a live activity feed on the BlackCloak app.[2]

BlackCloak monitors and analyzes content across multiple channels to detect disinformation campaigns or personal reputational threats before they escalate. BlackCloak monitors eight types of intelligence channels, including news, social media, court filings, and AI-generated content. BlackCloak says deepfake attacks can bypass email filters and awareness training. BlackCloak Impersonation Protection lets executives authenticate calls, texts, and video messages in real time. Executives can send an out-of-band authentication request and authenticate the source of calls, texts, video chats and emails.[2]

BlackCloak offers Physical Risk Reports that provide a shared intelligence picture. For these reports, intelligence from OSINT, deep and dark web sources specific to each executive is gathered. BlackCloak experts assess threat credibility and likely intent. Security teams receive early warnings with context in a downloadable report.

BlackCloak continuously monitors personal devices such as laptops, mobiles, and tablets in the background, securing them with enterprise-grade EDR. Executives install the BlackCloak app on their personal devices. BlackCloak performs security checks across six areas: passcode, biometrics, encryption, OS updates, breach status, and botnet activity. BlackCloak backs EDR and home network scanning with expert-led incident response from its in-house, US-based security operations center. BlackCloak manages detection, remediation, and incident response end-to-end.[2]

BlackCloak works with the customer team to identify who needs protecting and aligns with their assistants to book a confidential Privacy & Exposure Review. BlackCloak gives the customer team a dashboard with aggregated, anonymized metrics on risk exposure reduction that can be used to present to the board. CISOs and security teams have a dedicated account manager for questions on SLAs and billing and on the security of protected executives. BlackCloak operates outside of the customer's corporate cybersecurity technology stack. BlackCloak says it cannot see into executives' personal accounts or browsing history.[2][6]
