Insight Partners led the Series C financing, which included participation from Menlo Ventures, Citi Ventures and Goldman Sachs Asset Management.
"With cyber risk becoming a problem for a growing number of business functions, cybersecurity knowledge and skills should no longer be the preserve of a few technical people hidden away in a back office. Everyone from the teams who build software, to the CEO, now need to play their part in addressing a pervasive company issue. This requires unlocking and evidencing skills in a much broader group of people."
Breed Reply, Wentworth, Mainport Innovation Fund II, and Enterprise M3 backed the latest financing round.
"This funding will enable us to further develop our global presence and provide an enhanced level of protection to a growing number of customers in the rail industry. We have enjoyed both financial and strategic support from our investors and we will look to deliver significant value to them from this further investment."
The funding round was backed by Skyscanner co-founder Gareth Williams alongside Scottish Enterprise and Equity Gap.
"This is hugely exciting news and is a change of trajectory from our original, more modest ambitions – we are now set on the path for Boundary to become a top-tier European home security business. To have someone with the calibre of Gareth giving our product his backing and mentorship is incredible; we have massive plans for the future."
March Capital led the Series C round, which values the enterprise security firm at $500m and brings total funding to over $120m.
"The security of our operations and data is paramount to the success of Arm, and we’re committed to empowering our people to make sound security decisions while doing their jobs effectively. The concept of human layer security is becoming a critical part of doing business today. Tessian enables us to reduce risk across the organization by providing valuable tools and knowledge to not only stop threats like advanced phishing attacks and accidental data loss, but also continually improve the security behaviors of our teams as the threat landscape evolves."
