Challenges for Security as a Service (SECaaS)

With so many advantages SECaaS also has a few disadvantages too which create challenges for SECaaS such as:

  • High vulnerability against large-scale attacks - SECaaS handles security uniformly in a similar manner hence, if there is a security breach that happens only for one request, security is broken down for all requests. Businesses cannot afford to keep their data loose and vulnerable to hacker attacks.
  • Data Storage locations – SECaaS stored backed up data offsite at different places of the world. Hence, the employer can never be sure about the physical reliability of the data in that server. Nothing can be done to prevent a physical stealing attempt and relying on authorities.

The major challenge for the SECaaS is to maintain a reputation of reliability and superiority to standard non-cloud services.
