About Keepnet Labs

Keepnet Labs sells security awareness training and multi-channel phishing simulations. Keepnet sells a plan that adds incident response for the emails, SMS and calls employees report, and before and after behaviour measurement. Signals from the security stack a customer already runs become named behaviours in Keepnet.[4][7][9]

Keepnet sends a nudge in the moment, then training for the same behaviour. Keepnet nudges are short reminders by email, SMS and Teams, timed to each employee's behaviour. Keepnet security awareness training is matched to role, risk and behaviour, with nudges. Compliance 360 is role-based compliance training and readiness tracking. Secure Behaviour Dashboard shows before and after behaviour change, and risky behaviour from security tools drives nudges, training and simulations. Keepnet executive and advanced reports are ready-made reports with before and after behaviour data.[7][9]

Phishing Simulator runs email phishing simulations, with templates across languages and difficulty levels. Keepnet voice phishing simulations use pre-recorded, text-to-speech or two-way AI calls. Keepnet runs voice phishing simulations from numbers it owns, not spoofed. Keepnet places the call and records what each employee does. Keepnet voice campaign setup starts when a customer adds phone numbers and then creates a voice campaign. Keepnet SMS phishing simulations use numbers that Keepnet provides. Keepnet callback phishing is an email that asks the employee to call a number. Keepnet email threat simulator tests how email defences handle realistic threats. Keepnet customers can run voice, SMS, email, QR code and callback simulations themselves from the Keepnet console.[2][7][9][14][15]

Incident Responder provides analysis and response for reported emails, SMS and calls. Keepnet threat sharing lets customers share and receive phishing intelligence with peers. Keepnet says AI agents run the loop and, by default, nothing goes out until the customer approves it. Keepnet states that customer data is not used to train AI models.[3][7][9]

Senior Keepnet social engineers hold the calls themselves, with no AI voices. Keepnet vishing assessments are requested most for the help desk, and any team that takes calls can be included. Password and MFA resets, account changes and callbacks to the number on file are the most common scopes of a Keepnet vishing assessment. Keepnet vishing assessment callers are UK, Europe and US callers, in English and Spanish. Card, health, government ID and other high-sensitivity data are never requested or recorded in a Keepnet vishing assessment. Keepnet vishing assessment findings point to the verification steps and policies to strengthen, not to individual employees. Keepnet vishing assessment recordings are encrypted and deleted within five business days of report acceptance, under EU and UK GDPR and the published DPA. In a Keepnet vishing simulation, a platform the customer's team controls runs AI-agent, text-to-speech or recorded calls.[15]

Keepnet offers hosting in the region the customer chooses: the UK, EU, US, Canada, the UAE or Türkiye. Microsoft Azure hosts every Keepnet region except Türkiye, which AWS hosts. Keepnet lists certified security of ISO/IEC 27001, with data in the region the customer chooses. Keepnet states four current certifications, independently audited. Keepnet lists AES-256 at rest and TLS 1.2 or 1.3 in transit.[9][15]

Keepnet prices its plans per employee per month, billed annually, on a 3-year agreement, excluding tax, and 1-year agreements are quoted. Customers buying through a Keepnet partner have the partner quote, bill and support them. Keepnet names Whitbread and Koton among the teams it describes with the numbers they moved.[5][6][7][8][9][10][11][14][15]
