Vendor lineage
Netskope
Started from the observation that nobody knew which cloud applications their own staff were using.
Netskope was founded in 2012 by Sanjay Beri and others, at the point where software as a service had quietly become the way work was done and security teams had no visibility into any of it.
The founding observation was specific and easy to verify: ask an organisation how many cloud applications it uses, and the answer is invariably an order of magnitude lower than the truth. Staff adopt tools without procurement, data moves into services nobody approved, and a perimeter firewall sees encrypted traffic to a hosting provider and can say nothing useful about it.
Cloud access security brokers answered the visibility half. The harder half was doing something about it without blocking work, which requires understanding the ACTIVITY inside an application rather than the application itself - the difference between uploading to a corporate tenant and uploading the same file to a personal one, which look nearly identical on the wire.
That distinction is why the product had to understand application semantics rather than just domains, and it is the reason the category could not be served by a proxy that only saw hostnames.
The market has since folded CASB into security service edge, combining it with secure web gateway and zero-trust access, and Netskope built its own global network, NewEdge, rather than renting capacity - a capital decision that only makes sense if you believe inspection has to happen close to the user.
Founding stories
Netskope
Sanjay Beri left a vice presidency at Juniper Networks in 2012 convinced that the perimeter was already gone: work was moving into SaaS and cloud faster than any firewall could follow. With three fellow Juniper engineering veterans - Lebin Cheng, Ravi Ithal, and Krishna Narayanaswamy - he founded Netskope to see and govern that traffic itself, app by app, activity by activity. The company became a defining name in the brand-new CASB category, then spent the next decade building outward from it into the full cloud security edge.
The timeline
- Founded by Juniper alumni
Netskope starts in Santa Clara with a contrarian premise: the interesting traffic is no longer on your network, so security has to move to where the users and the SaaS are. Accel and Lightspeed back the early rounds.
- The CASB years
As 'cloud access security broker' enters the analyst vocabulary, Netskope's deep API plus inline coverage of thousands of SaaS apps makes it one of the category's reference implementations - visibility and control at the granularity of a single action inside an app.
- From CASB to SASE
Remote work makes the thesis mainstream overnight. Netskope expands into secure web gateway and zero trust network access, carried on NewEdge - its own private security cloud, built out to serve inspection close to every user rather than backhauled through choke points.
- A $7.5 billion private valuation
July 2021: a $300 million round led by ICONIQ values the company at $7.5 billion, funding the NewEdge buildout and the run at the converged edge market.

- Leader in the first SSE Magic Quadrant
Gartner carves Security Service Edge out of SASE and names Netskope a Leader in the inaugural Magic Quadrant - placement it has held as the category matured. Borderless SD-WAN (from the Infiot acquisition) completes the single-vendor SASE picture.
- IPO: NTSK
September 18, 2025: Netskope lists on Nasdaq as NTSK after pricing at $19 - the top of a raised range - collecting $908 million in one of the year's marquee security debuts; shares open at $23 for a market value around $8.6 billion. ARR stands at $707 million, up 33 percent.

The accreditation sprint: Administrator, Integrator, and Architect earned across 2024 to 2026, and Netskope Certified Cloud Security Instructor in 2025 - SSE taught from inside the category's defining vendor.
- Netskope One
The platform era: security and networking services converged as Netskope One, spanning SSE, SD-WAN, and digital experience management on NewEdge - and, increasingly, controls for enterprise AI usage.
Flagship products and solutions
- Netskope OneThe converged platform: CASB, secure web gateway, ZTNA, firewall, DLP, and SD-WAN delivered as one cloud service with a single policy model.
- Next Gen Secure Web GatewayInline inspection of web and cloud traffic with the app- and activity-level context Netskope is known for.
- Netskope Private AccessZero trust network access: user-to-application connectivity that never puts the user on the network.
- NewEdgeThe privately operated security cloud behind it all - inspection points spread across dozens of regions, peered directly with the big SaaS and cloud providers so security does not cost latency.
Key innovations
- Activity-level cloud visibilityNot just 'which app' but 'which action in which app instance by which user' - the granularity that defined CASB and still distinguishes cloud-native inspection from port-and-protocol firewalls.
- A private security cloudNewEdge: building and peering its own global inspection network instead of renting public cloud regions - performance as a security feature.
- Single-vendor SASE from the security sideGrowing from CASB to full SSE and then adding the WAN - the reverse of the networking vendors' route into the same market.
Main markets
Netskope competes at the center of the SSE and SASE market against Zscaler, Palo Alto Networks, Cisco, and Broadcom, serving more than 4,300 customers including over 30 of the Fortune 100 - enterprises replacing web proxies, VPNs, and branch security stacks with cloud-delivered inspection.
Analyst standing
- A Leader in Gartner's Security Service Edge Magic Quadrant from its inaugural 2022 edition onward - the analyst framing that turned the company's founding thesis into a named market.
