It classifies and mitigates bots through device fingerprinting, behaviour analysis and JavaScript challenges. [Block Akamai Bot Manager until consent](https://app.flowconsent.com/auth/sign-up?utm_source=flowconsent.com\&utm_medium=referral\&utm_campaign=security) · [Scan my site](https://www.flowconsent.com/en/scan) At a glance - Category [Security](https://www.flowconsent.com/en/services/security) - Consent Essential - Prior consent Not required - Documented cookies 4 - Third-party domains 4 - Servers Akamai Intelligent Platform edge with EU points of presence; centralised analytics in the United States Overview ## What does Akamai Bot Manager do? Akamai Bot Manager is a bot detection and mitigation product that runs on the Akamai Intelligent Platform, the world's largest content delivery network. It analyses every request reaching your site, scores it against bot signatures and machine learning models, and applies the action you configured (allow, monitor, slow down, serve alternate content, challenge with a JavaScript test or a captcha, block). ## **What Akamai Bot Manager does** Bot Manager Premier injects a JavaScript sensor that fingerprints the device, captures behavioural signals (mouse movements, scrolling, typing cadence), and posts the proof of work back to the Akamai edge. The edge stores a bot score in a signed cookie so subsequent requests do not require revalidation. Akamai threat intelligence updates the rules continuously from the global Akamai network. ## **Cookies and data collected** The platform sets first party cookies on the protected domain (typically \_abck for the score, bm\_sz for the session, ak\_bmsc for behaviour) and reads the IP, user agent, TLS fingerprint, the device sensor payload, and request headers. None of the cookies is used for marketing. ## **GDPR and ePrivacy implications** The bot scoring cookies can be considered strictly necessary for security under Article 5(3) ePrivacy, since they directly support the integrity of the service. The behavioural signals are personal data and rely on legitimate interest (Article 6(1)(f) GDPR) with a documented balancing test. Akamai is a processor under your DPA. Inform users in your privacy notice that bot management is used. ## **Data hosting and transfers** Edge evaluation happens close to the visitor (including EU points of presence). Akamai Technologies is a US company and the central threat intelligence platform runs in the US. Transfers are covered by the EU-US Data Privacy Framework (Akamai is certified) and by Standard Contractual Clauses for non DPF flows. ## **How to deploy it compliantly** Treat Bot Manager as a strictly necessary security tool, enabled by default. Restrict the sensor to pages where bot risk justifies it (login, checkout, search), keep the cookies on the first party domain, and document the deployment in your record of processing activities. Provide an accessible alternative for users blocked by false positives. Compliance ## Akamai Bot Manager and the GDPR - Legal basis Legitimate interest (Art. 6(1)(f) GDPR) for security, fraud and bot prevention, with documented balancing test; the bot scoring cookie can be considered strictly necessary - Risk level medium - Applicable regulations GDPR, ePrivacy Directive, NIS2, EU-US Data Privacy Framework, EDPB Guidelines 5/2020 on consent ### Impact assessment (DPIA) A DPIA is recommended when Bot Manager runs on consumer journeys (login, account creation, checkout) where false positives could exclude legitimate users. Document the signals captured by the sensor (device, behaviour), the retention by Akamai, the EU edge architecture, and the appeal path for users blocked by mistake. ### Sample text for your banner > We use Akamai Bot Manager to protect this site against automated abuse, fraud and credential stuffing.

Bot Manager typically sets \_abck (bot score), bm\_sz (session), ak\_bmsc (behavioural state) and bm\_sv (sensor verification) as first party cookies on the protected domain. Lifetimes range from session to one year. They are not used for marketing. ### Does Akamai Bot Manager require GDPR consent? Generally no. The cookies and the sensor are used to protect the integrity of the service and qualify as strictly necessary under Article 5(3) ePrivacy.

Legitimate interest under Article 6(1)(f) GDPR for fraud and bot prevention, with a documented balancing test.

Akamai Technologies is a US company and central analytics run in the United States. Transfers rely on the EU-US Data Privacy Framework and on SCCs for any non DPF flow. ### Do I need a DPIA? A DPIA is recommended for deployments on consumer flows where false positives could impact rights (login, account creation, payment). Document the signals, the impact on accessibility, the appeal mechanism, and the retention of bot scores. ### How do I implement Akamai Bot Manager compliantly? Enable Bot Manager on critical surfaces (login, password reset, search) rather than every page. Keep the cookies first party. Document the legitimate interest balancing test. Provide an alternative path for users blocked by mistake. ### Are there alternatives to Akamai Bot Manager?
