The US Securities and Exchange Commission is cracking down on four companies for failing to disclose the full scope of how the SolarWinds hack impacted their businesses.

The four companies—IT security providers Check Point and Mimecast, IT solutions provider Unisys, and cloud collaboration software maker Avaya—have agreed to pay fines for allegedly downplaying the breach in public filings.

The 2020 SolarWinds hack involved suspected Russian hackers breaking into numerous US government agencies and private companies by tampering with software updates from SolarWinds, a Texas-based IT company that served thousands of enterprise customers. 

The four companies learned they had been ensnared in the SolarWinds hack in 2020 and 2021. “But each negligently minimized" the incident in public disclosures, the SEC alleges. 

In Unisys’s case, the company described the breach as “hypothetical despite knowing that it had experienced two SolarWinds-related intrusions involving exfiltration of gigabytes of data,” the SEC says. Meanwhile, Avaya told investors the hacking incident had only affected a limited number of company email messages when, in reality, the hackers accessed at least 145 files. Unisys must now pay a $4 million civil penalty, while Avaya has agreed to pay $1 million. 

As for Check Point, it “knew of the intrusion but described cyber intrusions and risks from them in generic terms,” the SEC says. Mimecast allegedly tried to minimize the breach by failing to disclose what kind of computer code the hackers had stolen from the company and the quantity of encrypted credentials” that had been looted. Both will now pay about $990,000 as a fine. 

“In two of these cases, the relevant cybersecurity risk factors were framed hypothetically or generically when the companies knew the warned of risks had already materialized,” says SEC Acting Chief of the Crypto Assets and Cyber Unit Jorge Tenreiro. “The federal securities laws prohibit half-truths, and there is no exception for statements in risk-factor disclosures.”

The SEC requires listed companies to publicly report significant data breaches within four business days. The increased scrutiny might motivate the private sector to treat IT security more seriously as ransomware attacks and other hacking incidents become all too common. 

The four companies didn’t immediately respond to a request for comment. However, according to the SEC, each “agreed to cease and desist from future violations of the charged provisions and to pay the penalties.”

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
