Open source software is now a $14 billion+ market and growing fast, in use in one way or another in 95 percent of all enterprises. But that expansion comes with a shadow: open source components can come with vulnerabilities, and so their widespread use in apps becomes a liability to a company’s cybersecurity.
Now, a startup out of the UK called Snyk, which has built a way to detect when those apps or components are compromised, is announcing a $22 million round of funding to meet the demand from enterprises wanting to tackle the issue head on.
Led by Accel, with participation from GV plus previous investors Boldstart Ventures and Heavybit, this Series B notably is the second round raised by Snyk within seven months — it raised a $7 million Series A in March. That’s a measure of how the company is growing (and how enthusiastic investors are about what it has built so far). The startup is not disclosing its valuation but a source close to the deal says it is around $100 million now (it’s raised about $33 million to date).
As another measure of Snyk’s growth, the company says it now has over 200 paying customers and 150,000 users, with revenues growing five-fold in the last nine months. In March, it had 130 paying customers.
(Current clients include ASOS, Digital Ocean, New Relic and Skyscanner, the company said.)
Snyk plays squarely in the middle of how the landscape for enterprise services exists today. It provides options for organisations to use it on-premises, via the cloud, or in a hybrid version of the two, with a range of paid and free tiers to get users acquainted with the service.
Guy Podjarny, the company’s CEO who co-founded Snyk with Assaf Hefetz and Danny Grander, explained that Snyk works in two parts. First, the startup has built a threat intelligence system “that listens to open source activity.” Tapping into open-conversation platforms — for example, GitHub commits and forum chatter — Snyk uses machine learning to detect potential mentions of vulnerabilities. It then funnels these to a team of human analysts, “who verify and curate the real ones in our vulnerability DB.”
Second, the company analyses source code repositories — including, again, GitHub as well as BitBucket — “to understand which open source components each one uses, flag the ones that are vulnerable, and then auto-fix them by proposing the right dependency version to use and through patches our security team builds.”
Open source components don’t have more vulnerabilities than closed source ones, he added, “but their heavy reuse makes those vulnerabilities more impactful.” Components can be used in thousands of applications, and by Snyk’s estimation, some 77 percent of those applications will end up with components that have security vulnerabilities. “As a result, the chances of an organisation being breached through a vulnerable open source component are far greater than a security flaw purely in their code.”
Podjarny says the plan is not to tackle proprietary code longer term but to expand how it can monitor apps built on open source.
“Our focus is on two fronts – building security tools developers love, and fixing open source security,” he said. “We believe the risk from insecure use of open source code is far greater than that of your own code, and is poorly addressed in the industry. We do intend to expand our protection from fixing known vulnerabilities in open source components to monitoring and securing them in runtime, flagging and containing malicious and compromised components.”
While this is a relatively new area for security teams to monitor and address, he added that the Equifax breach highlighted what might happen in the worst-case scenario if such issues go undetected. Snyk is not the only company that has identified the gap in the market. Black Duck focuses on flagging non-compliant open source licences, and offers some security features as well.
However, it is Snyk — whose name derives from a play on the word “sneak”, combined with the acronym meaning “so now you know” — that seems to be catching the most attention at the moment.
“Some of the largest data breaches in recent years were the result of unfixed vulnerabilities in open source dependencies; as a result, we’ve seen the adoption of tools to monitor and remediate such vulnerabilities grow exponentially,” said Philippe Botteri, partner at Accel, who is joining the board with this round. “We’ve also seen the ownership of application security shifting towards developers. We feel that Snyk is uniquely positioned in the market given the team’s deep security domain knowledge and developer-centric mindset, and are thrilled to join them on this mission of bringing security tools to developers.”
