With many businesses knowing that they need a specialized cloud security solution, there is a doubt of whether or not a Cloud Access Security Broker (CASB) is enough for data security. However, there is a new technology on the rise, which is Secure Access Service Edge (SASE). This technology not only delivers every capability of CASB but also offers extra security solutions in combination with zero-trust capabilities that work beyond the cloud. However, there are many pros and cons in the discussion of SASE vs CASB, which we are going to discuss here.

What Is CASB?

CASB stands for Cloud Access Security Broker, which is used for addressing the weaknesses of legacy network security models. This is a better option than the LAN, which was conventionally used by the organizations. The security of LAN was limited to the perimeter of the organization’s LAN and outer areas were not covered. CASB technology is useful to safeguard cloud data in a similar way to LAN technology. CASB can be implemented as a part of the Software as a Service (SaaS) model or as a physical device. In either case, it will ensure network visibility and threat safeguard for your company’s cloud applications.

Pros and Cons of CASB

Pros

  • Provides the capabilities of limited inline threat security.
  • Can be used along with other solutions to strengthen the security of your organization’s cloud infrastructure.

Cons

  • Requires integration with different standalone security solutions.
  • Decreases the overall efficacy of the security team, since there is a need to acquire, deploy, monitor, and maintain every security solution separately.

What Is SASE?

Software-Defined WAN (SD-WAN) is a networking solution that delivers dependable network connectivity and top performance by combining several transport links. It can route traffic amid SD-WAN appliances in the best manner, and hence it is the perfect choice for connecting organizations to all their cloud-based deployments. SASE stands for Secure Access Service Edge and it combines SD-WAN with a complete network security stack. The results are deployed via virtual appliances that are cloud-native.

Pros and Cons of SASE

Pros

  • The benefits of SASE technology are that comprehensive visibility is ensured into the traffic that is routed via the corporate WAN.
  • It also allows carrying out complete security inspections.
  • It is a complete WAN infrastructure solution, which means that it is not possible to slot into a place like in CASB.

Cons

  • It requires network redesign along with ending legacy networking & security solutions.
  • Hence, it is more costly.

SASE vs CASB which is Required for Your Organization?

In the discussion of SASE vs CASB, it is clear that it is better to implement only SASE in your organization since not only it simplifies the security but it also maximizes the efficiency of your organization’s security team. ASE combines CASB protection along with SD-WAN’s network routing feature and next-generation firewall (NGFW)’s security feature. However, CASB can be included as an add-on.
