A lot of enterprise cybersecurity efforts focus on malicious hackers that work on behalf of larger organizations, be they criminal groups or state actors -- and for good reason, since the majority of incidents these days come from phishing and other malicious techniques that originate outside the enterprise itself.
But there has also been a persistent, and now growing, focus also on "insider threats" -- that is, breaches that start from within organizations themselves. And today a startup that specialises in this area is announcing a round of growth funding to expand its reach.
Dtex, which uses machine learning to monitor network activity within the perimeter and around all endpoints to detect unusual patterns or behaviour around passwords, data movement and other network activities, is today announcing that it has raised $17.5 million in funding.
The round is being led by new investor Northgate Capital with Norwest Venture Partners and Four Rivers Group, both previous investors, also participating. Prior to this, the San Jose-based startup had raised $57.5 million, according to data from PitchBook, while CrunchBase puts the total raised at $40 million.
CEO Bahman Mahbod said the startup is not disclosing valuation except to say that it's "very excited" about it.
For some context, the company works with hundreds of large enterprises, primarily in the financial, critical infrastructure, government and defence sectors. The plan is to now extend further into newer verticals where it's started to see more activity more recently: pharmaceuticals, life sciences and manufacturing. Dtex says that over the past 12 months, 80% of its top customers have been increasing their level of engagement with the startup.
Dtex's focus on "insider" threats sounds slightly sinister at first. Is the implication here that people are more dishonest and nefarious these days and thus need to be policed and monitored much more closely for wrongdoing? The answer is no. There are no more dishonest people today than there ever have been, but there are a lot more opportunities to make mistakes that result in security breaches.
The working world has been on a long-term trend of becoming increasingly digitised in all of its interactions, and bringing on a lot more devices onto those networks. Across both "knowledge" and front-line workers, we now have a vastly larger number of devices being used to help workers do their jobs or just keep in touch with the company as they work, with many of them being brought by the workers themselves rather than being provisioned by the companies. There has also been a huge increase in cloud services,
And in the realm of "knowledge" workers, we're seeing a lot more remote or peripatetic working, where people don't have fixed desks and often work outside the office altogether -- something that has skyrocketed in recent times with stay-at-home orders put in place to mitigate the spread of COVID-19 cases.
All of this translates into a much wider threat "horizon" within organizations themselves, before even considering the sophistication of external malicious hackers.
And the current state of business has exacerbated that. Mahbod tells us that Dtex is currently seeing spikes in unusual activity from the rise in home workers, who sometimes circumvent VPNs and other security controls, thus committing policy violations; as well as more problems arising from the fact that home networks have been compromised and that is leaving work networks, accessed from home, more vulnerable. These started, he said, with COVID-19 phishing attacks but have progressed to undetected malware from drive-by downloads.
And, inevitably, he added that there has been a rise in intentional data theft and accidental loss arising in cases where organizations have had to lay people off or run a round of furloughs, but might still result from negligence rather than intentional actions.
There are a number of other cybersecurity companies that provide ways to detect insider threats -- they include CloudKnox and Obsidian Security, along with a number of larger and established vendors. But Mabhod says that Dtex "is the only company with 'next-generation' capabilities that are cloud-first, AI/ML baked-in, and enterprise scalable to millions of users and devices, which it sells as DMAP+.
"Effectively, Next-Gen Insider Threat solutions must replace legacy Insider Threat point solutions which were borne out of the UAM, DLP and UEBA spaces," he said.
Those providing legacy approaches of that kind include Forcepoint with its SureView product and Proofpoint with its ObserveIT product. Interestingly, CyberX, which is currently in the process of getting acquired by Microsoft (according to reports and also our sources), also includes insider threats in its services.
This is one reason why investors have been interested.
"Dtex has built a highly scalable platform that utilizes a cloud-first, lightweight endpoint architecture, offering clients a number of use cases including insider threat prevention and business operations intelligence," said Thorsten Claus, partner, Northgate Capital, in a statement. Northgate has a long list of enterprise startups in its portfolio that represent potential customers but also a track record of experience in assessing the problem at hand and building products to address it. "With Dtex, we have found a fast-growing, long-term, investible operation that is not just a band-aid collection of tools, which would be short-lived and replaced.”
