SASE or Secure Access Service Edge is a term that often appears in the world of computer networks. What is SASE and can SASE be a solution for today’s business companies, let’s discuss one by one in the articles below.

In today’s world of technology, it is growing very rapidly. This can be seen from the many technological innovations that were born with various new terms, starting from cybersecurity, such as CSIR, C2, SASE or SSE.
SASE itself is a trend in today’s cyber security. Where previously security and networking were managed separately, in SASE these two functions converge into one. In 2019, Gartner predicted that 40% of companies will plan to adopt SASE in 2024. But this study is different, in which different institutions say that 64% of companies will adopt SASE in 2022.

Get to Know Beforehand About SASE
SASE or Secure Access Service Edge is a network architecture that combines VPN and SD-WAN with cloud-like capabilities including security such as secure web gateways, cloud access security brokers, firewalls, and zero-trust network access. This capability is owned by the cloud network available as a service provided by SASE vendors.
SASE’s 5 Key Components
SASE itself consists of 6 important components starting from Software-defined WAN (SD-WAN), Cloud Access Security Broker (CASB), Firewall-as-a-Service (FWaaS), Secure Web Gateways (SWG), and Zero Trust Network Access. (ZTNA) following explanation:
Software-defined WAN (SD-WAN)
Wide Area Network or WAN is a traditional network architecture that combines various networks of branches into a single unit. SD-WAN is a software-defined WAN that forms an overlay architecture that uses routing or software to create virtual connections between endpoints in physical or logical form.
SD-WAN provides an almost unlimited network to be able to manage user traffic so as to optimize the user experience according to needs. Also has high flexibility in managing encryption and policies.
Cloud Access Security Brokers (CASB)
A cloud access security broker is a SaaS application whose job is to act as a security checkpoint between the local network and cloud applications and implement data security policies. With Cloud Access Security Broker able to protect data using prevention, monitoring and mitigation techniques. CASB is also capable of identifying malicious behavior and reporting it to administrators if any violations occur.
Firewall as a service moves firewall protection to the cloud, where it is no longer the traditional network perimeter. This also allows companies to take advantage of the company network for workers who work remotely or remotely safely. Companies can also implement security policies efficiently.
Secure Web Gateways (SWG)
Secure Web Gateways are web security services capable of filtering unauthorized data traffic and blocking certain networks. This SWG can contain threats before they spread to the virtual perimeter. SWG may also incorporate malicious code detection technologies, malware programs and URL filters.
Zero Trust Network Access (ZTNA)
Zero Trust Network Access is a set of cloud-based technologies that operate on a trust framework with minimum privileges across all users, devices, and applications.
This model requires all users to be authenticated, authorized, and validated before gaining access to company applications and personal data. With ZTNA addressing the poor user experience, complex operations, high costs, and risks of using conventional VPNs.
Thus the discussion above, we can conclude that SASE is a much cheaper enterprise network solution that integrates security networks with cloud networks more efficiently. How are you interested in implementing SASE in your company?
