Vendor lineage
Check Point Software Technologies
Patented stateful inspection, invented the firewall market, and then watched its own alumni build the competition.
Gil Shwed, Marius Nacht and Shlomo Kramer founded Check Point in Tel Aviv in 1993. Shwed had worked on network access separation during military service, and the company's founding product, FireWall-1, introduced stateful inspection to a commercial market that had been making do with packet filters and application proxies.
Stateful inspection is the idea worth understanding, because everything since assumes it. A packet filter judges each packet alone, which means it cannot tell a reply from an unsolicited connection and has to leave return ports open. An application proxy understands conversations but terminates them, which is slow and needs code per protocol. Stateful inspection tracked connections in a table and judged packets against that state - the security of understanding the conversation, at close to the speed of filtering.
Check Point patented it, sold it as software on general-purpose hardware, and effectively created the commercial firewall category. Through the late 1990s it held a dominant share of a market it had defined.
What happened next is the more interesting half. Nir Zuk, one of the first employees, left and eventually founded Palo Alto Networks, which overtook Check Point in firewall revenue around 2014. Shlomo Kramer, a co-founder, went on to found Imperva and later Cato Networks. The company's alumni network seeded a substantial part of the Israeli security industry, and several of its competitors.
Check Point itself remained independent, profitable and conservative through decades of consolidation - which on this timeline is genuinely rare. Almost every peer from 1993 has been acquired, split or renamed. It has been criticised for moving slowly on next-generation firewall features and cloud, and it is still here, still under its own name, still run for much of that time by a founder.
Founding stories
Check Point Software Technologies
Gil Shwed carried the idea out of Unit 8200, the Israeli signals-intelligence unit where he had connected classified networks: inspect traffic statefully, tracking connections rather than judging lone packets. With Marius Nacht and Shlomo Kramer and $250,000 of seed money from BRM, he built FireWall-1 - and with it, effectively, the commercial firewall market. Sun signed an OEM deal in 1994, HP a distribution deal in 1995, and by February 1996 IDC measured Check Point at forty percent of the world firewall market. Kramer left in 2003 to found Imperva, whose page also lives in this section; Shwed ran the company for thirty-one years, the longest CEO tenure on Nasdaq.
The timeline
- Stateful inspection
Founded in Ramat Gan on Shwed's core idea, patented as Stateful Inspection: a firewall that remembers connection state. FireWall-1 ships the next year, with VPN-1 among the first commercial VPN products close behind.
- Market leader, then IPO
IDC names Check Point the worldwide firewall market leader at a 40 percent share in February; the NASDAQ listing as CHKP follows the same year - Israel's security industry arrives on the world stage.
- The Nokia appliances come home
Check Point completes the acquisition of Nokia's security appliance business - the hardware line that had carried FireWall-1 into countless data centers - and consolidates software and metal under one roof, alongside the Software Blades architecture introduced the same year.
- Buying into the cloud era
Dome9 (~$175 million) brings cloud security posture management, opening an acquisition run that adds Avanan for cloud email security in 2021 - the CloudGuard and Harmony families take shape.
- Perimeter 81 and the SASE turn
The ~$490 million acquisition of Perimeter 81 pulls security service edge into the portfolio for hybrid work, folded into the Infinity platform alongside Quantum (network) and the 2024 Cyberint threat-intelligence purchase (~$186 million).
- The second CEO in thirty-one years
December 2024: Nadav Zafrir, Team8 co-founder and former commander of Unit 8200, becomes only the second CEO in company history; Gil Shwed moves to Executive Chairman - the firewall's inventor handing over the company it built.
