Vendor lineage
Pulse Secure
A company created to hold a product line older than itself.
Pulse Secure was formed in 2014 when Juniper sold its Junos Pulse business to Siris Capital. That is an unusual founding: the company existed on day one with a mature product, an installed base and a support obligation, and no history of its own at all.
The product was SSL VPN, which Juniper had acquired with NetScreen in 2004 and NetScreen had built on technology from Neoteris. So the code predates the company selling it by more than a decade, and the lineage runs through two acquisitions before the carve-out.
The market it served was the ordinary one: remote users needing access to internal applications without a full network-layer tunnel, authenticated at the edge and given only what policy allowed. Pulse Connect Secure appliances sat at that boundary in a very large number of enterprises and government networks, which is the detail that matters for what happened later.
Being a carve-out shapes a company. Private-equity ownership meant a focus on the installed base and maintenance revenue rather than on reinvention, and the codebase carried a decade of accumulated decisions made inside two previous owners.
Ivanti acquired Pulse Secure in the same announcement as MobileIron, completing on 1 December 2020. Serious vulnerabilities in those VPN appliances were subsequently exploited widely enough to draw emergency directives from national cyber agencies - which is the part of this history that most affected people who never bought anything from the company, since the appliances were sitting in front of networks that mattered.
It is a useful entry precisely because the failure was structural rather than careless. A product line inherited across three owners, each with different priorities and none having written it, is a specific kind of risk, and this timeline shows it happening repeatedly.
Founding stories
Pulse Secure
Pulse Secure was born a veteran. The product at its heart began as Neoteris's Instant Virtual Extranet - the appliance that defined clientless SSL VPN - which NetScreen bought in 2003 and Juniper inherited with NetScreen itself in 2004. Inside Juniper it became the SA series and then Junos Pulse, the remote-access standard of a corporate era; in 2014 Siris Capital carved the business out for roughly $250 million and Pulse Secure stood alone, one product family carrying four companies' history. This site's author met it from the distribution side, carrying Pulse in the ScanSource portfolio - while his own earlier chapter inside Juniper had overlapped the very years Junos Pulse took shape.
The timeline
- The Neoteris inheritance
NetScreen acquires Neoteris, whose Instant Virtual Extranet defined the clientless SSL VPN; Juniper's 2004 acquisition of NetScreen brings the line in-house - the story the NetScreen/Juniper page tells from the other side.

- Siris carves out Pulse Secure
Siris Capital acquires the Junos Pulse business from Juniper (~$250 million per press coverage), forming Pulse Secure LLC - the SSL VPN franchise as a standalone company, with mobile-security startup MobileSpaces bought the same year.
- Pulse One
Central policy management arrives, unifying secure access across endpoints and mobile devices to applications on-premises and in cloud - the portfolio widening beyond the gateway.
- The Zeus thread arrives
Pulse acquires Brocade's virtual ADC business - the load-balancing lineage that began at Zeus Technology and passed through Riverbed as SteelApp - briefly uniting two storied product bloodlines under one small vendor.

- Into Ivanti
September 28, 2020: Ivanti announces the acquisition of Pulse Secure from Siris (terms undisclosed) alongside MobileIron; both close December 1, 2020. Pulse Connect Secure becomes Ivanti Connect Secure - the remote-access line under its fifth flag.

Key innovations
- Clientless SSL VPNThe Neoteris design Pulse inherited put remote access in a browser - no fat client, no IPsec ceremony - and set the template enterprise VPNs followed for two decades.
- One product, five flagsNeoteris, NetScreen, Juniper, Pulse Secure, Ivanti: the same secure-access lineage carried through four acquisitions - networking's supply chain of ideas in a single product family.
Main markets
The Pulse portfolio now ships as Ivanti's secure-access line, defending a vast VPN installed base while the market's center of gravity shifts toward zero-trust network access - the incumbent estate every ZTNA vendor bids to replace.
Analyst standing
- For years the SSL VPN reference alongside Cisco and F5 in the secure-access evaluations - the standing that made the franchise worth carving out, and worth acquiring twice.
