About Ketch

Ketch sells privacy management software that keeps data clean, permissioned, and AI-ready. Ketch says its software lets customers power growth without regulatory or reputational risk. Ketch runs the consent, preference, and data-rights signals behind 3,500+ consumer brands, from global retailers to media networks, fintechs, and AI-native companies.^[3]

Ketch describes Discovery, Permissioning, and Growth as one value chain, not three products: find every data flow, enforce every permission, and activate the data you can trust. Permission Vault, Identity Sync, and Transponder are the foundations that keep the three layers connected. The Ketch Agent Network is the orchestration layer that powers every product in the Ketch platform, continuously gathering the context privacy teams need instead of chasing by hand: regulations, policies, contracts, data repositories, collection points, access controls, and Ketch configuration. The Ketch Agent Network does the actual work, turning insights to actions in real time.^{[1][3][7][11]}

Ketch AI Governance is anchored by AI Sentry, which intercepts prompts, detects PII, enforces consent in AI workflows, and blocks data leakage in real time. AI Sentry sits directly inside AI applications, intercepting prompts before they reach the LLM, detecting personal data leakage, and blocking or redacting PII at the point of use. AI Sentry helps surface and document model activity for emerging obligations such as the EU AI Act.^[4][8]

Data Sentry is a privacy pentest for a website, revealing privacy vulnerabilities before regulators or plaintiffs' attorneys find them. Data Sentry analyzes real-time network traffic, the actual data packets leaving a site. Data Sentry works alongside any CMP. Ketch research across 134 major websites found that 40% of trackers ignore consumer opt-outs. Iris is the patent-pending scanning algorithm from Ketch.^[6][9]

Ketch Data Mapping turns a sprawling tech stack into a defensible data map without months of interview cycles. Ketch connectors and detection agents reach directly into SaaS apps and internal data systems, with automated discovery across 400+ platforms. In data mapping, AI agents continuously detect systems, read contracts, and classify data, and that map is the record of processing activities (ROPA). Ketch ships templates for DPIAs, PIAs, TIAs, AI impact assessments, vendor reviews, and ROPA. The Ketch Agent Network drafts answers based on prior evidence, so reviewers focus on the decisions that actually need a human. Ketch data subject rights fulfillment can automate data subject requests (DSRs) from intake to fulfillment.^{[1][6][13][14]}

Ketch Identity Sync stitches together the many identifiers representing a person across browsers, devices, and platforms to build a unified identity graph. Ketch collects and links cookies, device IDs, hashed emails, and account IDs into a unified profile using deterministic connections only. Ketch Orchestration connects data collection to data use. Permission Vault enforces consent, jurisdiction, and policy on every downstream call. Ketch describes its Privacy 360 Analytics Suite as a defensible audit log for opt-out and compliance workflows. Ketch Marketing Preference Management links cookies, device IDs, hashed emails, and account logins into a single preference record, then syncs it to Salesforce, Segment, and Braze. Ketch Progressive Consent collects permissions contextually over time, placing consent requests at relevant moments in the shopping journey, such as loyalty sign-up, checkout, or content downloads.^{[4][6][7][10][15]}

Ketch helps security teams observe Shadow AI, detect risky data flows, and keep AI systems aligned to consent, policy, and audit evidence. Ketch data privacy software streamlines the mundane, repetitive aspects of a privacy program. Ketch says its software is easy for legal and marketing teams to use with a WYSIWYG, drag-and-drop interface. Ketch integrates with CRMs, CDPs, and marketing automation platforms. Educational institutions rely on Ketch to responsibly activate student data for personalized learning, institutional efficiency, and improved student engagement, without compromising privacy. Ketch Profile Management consolidates consent status, communication preferences, and declared information into a permission-aware profile for each student, applicant, or alum.^{[4][5][6][16][17]}
