Customer Story

NTT TechnoCross

NTT required a solution that had a global track record of adoption, operability that reduces operating load, availability that achieves stable operation, ease of implementation, usage not as an asset but as a service, and monthly payable usage fees.

  • Operational Stability

    NTT immediately noticed their website had stabilized

  • Reallocated Resources

    Automated threat analytics allowed NTT to redirect focus to other projects

  • Secured Services

    Visitor traffic to NTT’s website becomes manageable and secure

  • Continued Growth

    NTT looks to expand future system planning thanks to Cloud WAF

“I believe it is the best cloud WAF, as it is easy to introduce and implement. After implementing Imperva, countermeasures against specific threats have been off our radar in a good sense and we essentially leave things to Imperva.”
