What does SSE stand for?
SSE stands for Security Service Edge. Security service edge: cloud-delivered security services such as SWG, CASB and ZTNA. Combined with SD-WAN networking, it forms SASE.
SSE is a set of security services delivered from the cloud instead of from appliances in the office. The services usually counted in it are a secure web gateway that filters internet traffic, a cloud access security broker that controls the use of cloud applications, and zero trust network access that connects users to private applications one at a time. Users connect to the provider's network wherever they are, and the same policy follows them. SSE is the security half of SASE: add the networking half, SD-WAN, and the result is SASE.
SSE in practice: an example
A consultant works from hotel Wi-Fi. The agent on her laptop sends web traffic to the SSE provider, which blocks a phishing page and stops her uploading a client file to a personal storage site. To reach the company's internal time-sheet application she is given access to that one application, after her identity and her device are checked, without a full VPN tunnel into the network.
What SSE is confused with
SSE vs SASE: what is the difference?
SASE is SSE plus SD-WAN: security and wide-area networking from one cloud service. SSE is the security part alone, for organizations that keep their existing network. What SASE stands for
SSE vs VPN: what is the difference?
A traditional VPN puts the user's device on the corporate network. The zero trust component of SSE connects the user to individual applications only, after checking identity and device each time. What VPN stands for
Which exams cover SSE?
SSE is on the official CompTIA acronym list for two of the four exams covered here.
- Security+ SY0-801: 3.2 (Security Architecture).
- Network+ N10-009: 1.0 (Networking Concepts).
Each number is a CompTIA exam objective and the name in brackets is its domain. The exam puts the term in a scenario; it does not ask you to recite the expansion.
Check yourself: two practice questions
Written by CertSprint for this page. They are not taken from any exam.
1. A company wants to keep its current WAN but move web filtering, cloud application control and remote application access to a cloud-delivered service. Which term describes what it is buying?
- Security service edge
- A storage area network
- An uninterruptible power supply
- A content delivery network
Show the answer
A. Security service edge. Cloud-delivered security without the networking component is SSE. With SD-WAN included it would be SASE.
2. Which pairing is correct?
- SASE = SSE + SD-WAN
- SSE = SASE + SD-WAN
- SSE = SIEM + SOAR
- SASE = VPN + NAT
Show the answer
A. SASE = SSE + SD-WAN. SSE is the set of security services, and SASE adds software-defined wide-area networking to it.
