We Know the Challenges You Face With Dark Web Monitoring

Identity Monitoring on the dark web is becoming a high-value offering that many security and service providers want to add to their portfolio, yet adding these services can be extremely challenging due to several factors:

  • A threat landscape that continuously evolves as threat actors develop innovative techniques to target your customers’ valuable data
  • Insufficient in-house resources, expertise, or technologies to continuously monitor the Surface, Deep, and Dark Web, Social Media, and Data Brokers
  • Onerous data collection, processing, and protection requirements to collect, curate, and analyze massive volumes of data as well as compliance requirements to protect the processed data
