Google is paying $5.4 billion to buy Mandiant, a cybersecurity firm well-known for detecting and investigating intrusions from state-sponsored hacking groups. 

The search giant is buying Mandiant to bolster the IT security around Google’s cloud computing business, which serves enterprise clients and governments. 

“Today, organizations are facing cybersecurity challenges that have accelerated in frequency, severity and diversity, creating a global security imperative,” Google said in the announcement. 

Google called Mandiant “a recognized leader in strategic security advisory and incident response services.” This is a reference to how Mandiant is among the cybersecurity outfits corporations often call if they’ve suffered a hack, such as a ransomware attack. 

Mandiant will thoroughly investigate the intrusion to boot the hackers out and recover the business operations. For example, back in December 2020, Mandiant helped uncover the massive SolarWinds breach, which ensnared numerous US government agencies and likely originated from Russian state-sponsored hackers. 

“​​Mandiant’s more than 600 consultants currently respond to thousands of security breaches each year,” the cybersecurity firm said on Tuesday. “Paired with research from more than 300 intelligence analysts, these resulting insights are what power Mandiant’s dynamic cyber defense solutions.” 

Google plans on offering Mandiant’s cybersecurity services to its Google Cloud clients. This includes using Mandiant to help secure a client's IT defenses before an attack can occur. Customers will also be able to tap Mandiant’s “Automated Defense” tools to help them respond to potential intrusions.   

“Combined with Google Cloud’s cloud-native security offerings, the acquisition will help enterprises globally stay protected at every stage of the security lifecycle,” Google added. 

The deal also occurs as Google is competing with Amazon and Microsoft for enterprise customers in the cloud computing space. The Mandiant acquisition is intended to complement “Google Cloud’s existing strengths in security,” which include other security tools designed to harden a client’s defenses and detect malware programs. 

The acquisition should close later this year, pending regulatory approval.

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.
