“Musubu APIs are a great, highly affordable GDPR solution for building quick IP-inspection modules to control access to all our website client sites from outside the U.S. Highly recommend it for mobile app development too where geolocation plays a big role.”

Owner, VandalsSmile Digital Marketing
“The Musubu tool has been a great asset to our company and clients. It allows us to quickly filter out non-actionable [false positive] entities and focus on the true threats to the organization, hence increasing our efficiency and responsiveness to our clients.”
Stan Blanton
CTO, @Risk Technologies
“Musubu integration with our SIEM reduces time to action by as much as 25% relying on proofed information. Our cybersecurity threat hunters are able to action security events with a higher degree of confidence and focus more on containment and mitigation actions rather than context building activities.”
