Texas state police expands surveillance with PenLink’s controversial technology raising privacy concerns
"Texas State Police Gear Up for Massive Expansion of Surveillance Tech", 24 September 2025
In June, the Texas Department of Public Safety (DPS) signed an acquisition plan for a 5-year, nearly $5.3 million contract for a controversial surveillance tool called Tangles from tech firm PenLink, according to records obtained by the Texas Observer through a public information request. The deal is nearly twice as large as the company’s $2.7 million two-year contract with the federal Immigration and Customs Enforcement (ICE).
Why This Story?
In 2018, the U.S. Supreme Court ruled in Carpenter v. United States that police must have a warrant to obtain cell phone location data from service providers like AT&T and Verizon. But a $5.3 million state police contract for an AI-powered surveillance tool called Tangles enables police to track cell phones without a court order. ...
Tangles is an artificial intelligence-powered web platform that scrapes information from the open, deep, and dark web. Tangles’ premier add-on feature, WebLoc, is controversial among digital privacy advocates. Any client who purchases access to WebLoc can track different mobile devices’ movements in a specific, virtual area selected by the user, through a capability called “geofencing.” Users of software like Tangles can do this without a search warrant or subpoena. (In a high-profile ruling, the Fifth Circuit recently held that police cannot compel companies like Google to hand over data obtained through geofencing.) Device-tracking services rely on location pings and other personal data pulled from smartphones, usually via in-app advertisers. Surveillance tech companies then buy this information from data brokers and sell access to it as part of their products.
WebLoc can even be used to access a device’s mobile ad ID, a string of numbers and letters that acts as a unique identifier for mobile devices in the ad marketing ecosystem, according to a US Office of Naval Intelligence procurement notice.
Wolfie Christl, a public interest researcher and digital rights activist based in Vienna, Austria, argues that data collected for a specific purpose, such as navigation or dating apps, should not be used by different parties for unrelated reasons. “It’s a disaster,” Christl told the Observer. “It’s the largest possible imaginable decontextualization of data. … This cannot be how our future digital society looks like.”

The privacy implications of police using services—like Tangles—that provide location data are “identical” to the issues raised in the Carpenter case, Wessler said. That’s because location data harvested from apps, as opposed to that obtained from service providers, can be even more invasive, he said. “You can tell just as much about somebody’s GPS history from their apps as you can from their cell phone location data from their phone provider. And in some cases, you can tell more,” Wessler said.
Tangles is a product offered by the cybersecurity company Cobwebs Technologies, which was founded in Israel in 2014 by three former members of Israeli military special units. The company has said their products, which are marketed as open source intelligence (OSINT) tools, have been used to combat terrorism, drug smuggling, and money laundering, but Meta has accused the company of operating as a surveillance-for-hire outfit.

Christl, the Austria-based digital rights researcher, said that companies selling software that incorporates data harvested from mobile phone apps have greatly expanded the definition of OSINT tools. If a company has to buy personal data from third-party brokers to incorporate into a software that they sell to police, he said, then that isn’t really an open source tool.
Lipton, the investigative researcher at the Electronic Frontier Foundation, said that’s troubling for the public. “People don’t realize that some of this stuff comes with a high cost,” she said. “Both price-wise and privacy-wise.”
In a written statement, a PenLink spokesperson told the Observer their “open-source intelligence (OSINT) solutions are used to protect our communities from crime, threats, and cyber-attacks by providing seamless access to data that is publicly available. From a technology perspective, we want to note that we operate only according to the law, adhering to strict standards and regulations.” The spokesperson did not answer other specific questions.

DPS’ Intelligence and Counterterrorism division has used Tangles since 2021, as first reported by The Intercept. The agency first purchased the software as part of Governor Greg Abbott’s multi-billion dollar Operation Lone Star border crackdown, doling out an initial $200,000 contract as an “emergency award” with no public solicitation. Each year since, DPS has expanded the contract: In 2022, it paid $300,000, and in 2023, more than $400,000, according to contracting records on DPS’ website. The agency’s new plan for a 5-year Tangles license, from 2024 through 2029, will cost about $1 million per year.
...
In its acquisition plan, DPS states that Intelligence and Counterterrorism division personnel need the tool to “identify and disrupt potential domestic terrorism and other mass casualty threats.” ...
It is unclear how DPS has used Tangles or whether the software has helped stop any potential mass shootings. DPS did not respond to written questions or an interview request for this story.
Following initial publication of this story, Republican state Representative Brian Harrison said on social media that he would be requesting more information from DPS about its use of the surveillance software. Reached by phone, Harrison told the Observer: “I want to make sure that we don’t have Fourth Amendment violations going on here, whether it’s intentional or not. … Government should be protecting our civil liberties, not violating them.”
After DPS purchased the initial license for Cobwebs’ software in 2021, local Texas law enforcement agencies followed suit. Operation Lone Star spending records from the Goliad County Sheriff’s Office, obtained by the Observer, show that the Goliad sheriff obtained a “cooperative use of [Cobwebs] software” in fall 2023 along with the sheriffs of Refugio and Brooks counties to “identify, link, and track the movements of cartel operatives throughout the region.”
Other Texas clients that have purchased Cobwebs’ software include the Dallas and Houston police departments and the sheriff’s office in Jackson County, which shares access with the Matagorda County Sheriff’s Office, according to local government meeting minutes and DPS emails.

Prior to its acquisition by PenLink, Cobwebs Technologies received backlash for how clients used its products. In 2021, Meta banned seven companies—including Cobwebs—that it had identified as participating in an online surveillance-for-hire ecosystem. As part of its sanctions, Meta removed 200 accounts operated by Cobwebs and its customers. In a company report, Meta investigators wrote that they identified Cobwebs customers in Bangladesh, Hong Kong, the United States, New Zealand, Mexico, Saudi Arabia, Poland, and other countries.
Cobwebs’ customers were not solely focused on public safety activities, Meta’s report said. “We also observed frequent targeting of activists, opposition politicians and government officials in Hong Kong and Mexico,” the report stated.
Agencies across the globe have used Tangles. From at least 2021 to 2022, Salvadoran police used it, according to the investigative outlet El Faro. Police in Mexico have also purchased the software, according to Excelsior, a Mexico City newspaper.
In 2022, a Cobwebs Technologies sales rep asked a DPS employee if the state agency could serve as a customer referral for a police agency in Israel, according to an email obtained by the Observer. In the email, the sales rep stated that DPS had at least 20 Tangles users at the time. DPS’ new acquisition plan allows for 230 named users.
Wessler, the ACLU attorney, said the sale of mobile device data to third-party data brokers and surveillance tech firms remains a legal gray area. “There are some legal frameworks that get at the edges of this, but there’s a whole kind of core of issues that the law just hasn’t caught up to,” Wessler said.
