Window Snyder’s new startup Thistle Technologies raises $2.5M seed to secure IoT devices


The Internet of Things has a security problem. The past decade has seen wave after wave of new internet-connected devices, from sensors through to webcams and smart home tech, often manufactured in bulk but with little — if any — consideration to security. Worse, many device manufacturers make no effort to fix security flaws, while others simply leave out the software update mechanisms needed to deliver patches altogether.
That sets up an entire swath of insecure and unpatchable devices to fail, and destined to be thrown out when they break down or are invariably hacked.
Security veteran Window Snyder thinks there is a better way. Her new startup, Thistle Technologies, is backed with $2.5 million in seed funding from True Ventures with the goal of helping IoT manufacturers reliably and securely deliver software updates to their devices.
Snyder founded Thistle last year, and named it after the flowering plant with sharp prickles designed to deter animals from eating them. “It’s a defense mechanism,” Snyder told TechCrunch, a name that’s fitting for a defensive technology company. The startup aims to help device manufacturers without the personnel or resources to integrate update mechanisms into their device’s software in order to receive security updates and better defend against security threats.
“We’re building the means so that they don’t have to do it themselves. They want to spend the time building customer-facing features anyway,” said Snyder. Prior to founding Thistle, Snyder worked in senior cybersecurity positions at Apple, Intel, and Microsoft, and also served as chief security officer at Mozilla, Square, and Fastly.
Thistle lands on the security scene at a time when IoT needs it most. Botnet operators are known to scan the internet for devices with weak default passwords and hijack their internet connections to pummel victims with floods of internet traffic, knocking entire websites and networks offline. In 2016, a record-breaking distributed denial-of-service attack launched by the Mirai botnet on internet infrastructure giant Dyn knocked some of the biggest websites — Shopify, SoundCloud, Spotify, Twitter — offline for hours. Mirai had ensnared thousands of IoT devices into its network at the time of the attack.
Other malicious hackers target IoT devices as a way to get a foot into a victim’s network, allowing them to launch attacks or plant malware from the inside.
Since device manufacturers have done little to solve their security problems among themselves, lawmakers are looking at legislating to curb some of the more egregious security mistakes made by default manufacturers, like using default — and often unchangeable — passwords and selling devices with no way to deliver security updates.
California paved the way after passing an IoT security law in 2018, with the U.K. following shortly after in 2019. The U.S. has no federal law governing basic IoT security standards.
Snyder said the push to introduce IoT cybersecurity laws could be “an easy way for folks to get into compliance” without having to hire fleets of security engineers. Having an update mechanism in place also helps to keeps the IoT devices around for longer — potentially for years longer — simply by being able to push fixes and new features.
“To build the infrastructure that’s going to allow you to continue to make those devices resilient and deliver new functionality through software, that’s an incredible opportunity for these device manufacturers. And so I’m building a security infrastructure company to support that security needs,” she said.
With the seed round in the bank, Snyder said the company is focused on hiring device and back-end engineers, product managers, and building new partnerships with device manufacturers.
Phil Black, co-founder of True Ventures — Thistle’s seed round investor — described the company as “an astute and natural next step in security technologies.” He added: “Window has so many of the qualities we look for in founders. She has deep domain expertise, is highly respected within the security community, and she’s driven by a deep passion to evolve her industry.”
