How We Test Antivirus Software

Protecting your devices from viruses and other malware is incredibly important, but effective antivirus detection isn’t the only thing to consider when choosing security software. You also want to ensure that the program won’t slow your devices down or interfere with everyday tasks. And if you’re buying a full cybersecurity suite, you’ll need to make sure it covers most or all of your security needs. Our testing processes are designed to help you find antivirus tools that meet all of these crit

Best King-Size Mattresses for 2025, Tested by CNET’s Sleep Experts

Our sleep experts have been testing mattresses, bedding and accessories for years (a few have been testing for up to eight years). At this point, we've tested over 300 mattresses from dozens of brands, from bigwigs like Purple and Tempur-Pedic to more niche companies like Sonu and Airweave. Our team is comprised of bed testers with varying body weights and types, heights, genders and sleep preferences, which helps us provide an overarching assessment of each mattress from a multitude of viewpoi

Galaxy Watch users might want to stay away from testing QPR1 betas

Ryan Haines / Android Authority TL;DR Galaxy Watch owners are reporting problems when using Samsung’s wearables with Android 16 QPR1 beta releases. Issues include failure to pair, connections dropping, and Samsung apps repeatedly crashing. For the moment, the only permanent solution seems to be going back to Android 16 stable. Getting early access to in-development software can be a lot of fun. Plenty of us participate in testing programs for some of our favorite apps, both in the interest o

This Guy Attached 21 Chef’s Knives to a Slicing Robot Arm to Determine Which One Is Best

After the fifth tomato, I had to know how my knife did. Without judgment, Heimendinger announced that it placed "second to last in the cohort." I felt responsibility for this knife, and a little embarrassment, until I remembered his knives came straight out of the box and into the testing process with an unblemished factory edge. My knife, on the other hand, had been in regular use in my test kitchen for more than six months receiving only the occasional honing. Plus, I noted protectively that t

Waymo to begin testing in Philadelphia with safety drivers behind the wheel

Waymo said it will begin testing in Philadelphia, with a limited fleet of vehicles and human safety drivers behind the wheel. "This city is a National Treasure," Waymo wrote in a post on X on Monday. "It's a city of love, where eagles fly with a gritty spirit and cheese that spreads and cheese that steaks. Our road trip continues to Philly next." The Alphabet -owned company confirmed to CNBC that it will be testing in Pennsylvania's largest city through the fall, adding that the initial flee

Nothing's untestable

Vidhi Katkoria Technical Writer Nothing's untestable As the co-founder of HashiCorp, Mitchell has been instrumental in the development of tools that many of us use daily, like Vagrant, Terraform, Vault, and more. He also helped shape the initial testing strategies for them, gaining hard-won insights into testing complex software along the way. At BugBash, where everyone is a testing nerd (or at least wants to be), most of us have come across that one piece of code that cannot be tested. What d

I Found the Best Way to Stop Mosquitos This Summer, and It's Not a Spray or Candle

Longer, hotter summers mean one thing: longer, itchier, angrier mosquito seasons. And if June's sizzling heat waves are any preview of summer's dog days, you're gonna need more than good vibes and a flickering citronella candle to make it through. I was playing it fast and loose with the usual bug defenses: sprays that smell bad and taste even worse and candles that burn out faster than your will to be outside. Then I met my new summer MVP: the Thermacell. It's a compact, affordable, bug-repell

Air quality tests around xAI’s Memphis data center raise questions

Elon Musk’s xAI is the subject of scrutiny in Memphis, where natural gas turbines powering its Colossus data center have raised alarm among residents concerned about air pollution. On Tuesday, the City of Memphis released the results of initial air quality testing performed by a third party, saying that levels of the 10 pollutants tested were not dangerous. But the Southern Environmental Law Center (SELC), which is threatening to sue xAI on behalf of the NAACP, said that the tests omitted a key

How Today’s Pentest Models Compare and Why Continuous Wins

As threat actors grow faster, stealthier, and more persistent, the approach to pentesting needs to keep evolving. Traditional, periodic assessments no longer keep up with rapidly changing attack surfaces. Static tests offer a snapshot, but attackers see a live stream. Security testing needs to shift testing models to mirror how real-world attackers operate. At Sprocket Security, our Continuous Penetration Testing (CPT) solution is an always on, always active, and hybrid pentesting model. In th

Best Meat Thermometers for 2025

James Bricknell/CNET The most important part of any thermometer testing is accuracy. We weight this criteria most heavily when compiling entries to the best list, and it is the most scientific of the tests. We use a medical-grade thermometer as our baseline for accuracy and test the meat probe variance to that temperature. Ice water testing Testing the accuracy of a thermometer usually involves a cup, some ice cubes, and water. Due to the nature of water it can be a liquid and a solid at 32F

The Best Water Filter Pitcher for 2025

As mentioned earlier in this article, there are quite a variety of contaminants worth removing from your tap water. The team here at our lab settled on three primary tests to benchmark the efficacy of these filters: TDS, pH and chlorine. Before we began the actual testing process, each pitcher was removed from the packaging, cleaned and then prepared per the manufacturer's instructions. This is very important, as most of these filters utilize activated carbon filtration, which will deposit sedim

So... You Want to Become a Penetration Tester?

Cybersecurity is a rapidly growing and evolving field with a wide range of subfields and specializations. One of these is penetration testing, a discipline within what's known as "red teaming," which seeks to actively find and exploit vulnerabilities within computer systems (with permission, of course). It's an exciting and rewarding career, and I'll show you how to become a penetration tester. Before I continue, however, let me be transparent about my own experience. While I have about three

The Pentagon is gutting the team that tests AI and weapons systems

It is a significant overhaul of a department that in 40 years has never before been placed so squarely on the chopping block. Here’s how today’s defense tech companies, which have fostered close connections to the Trump administration, stand to gain, and why safety testing might suffer as a result. The Operational Test and Evaluation office is “the last gate before a technology gets to the field,” says Missy Cummings, a former fighter pilot for the US Navy who is now a professor of engineering

Spore.Bio raises $23M to apply machine learning to microbiology testing

Recalls in the food and beverage industry due to contamination incidents can be catastrophic for a company. Not only do companies have to pay fines and damages, but the impacts on the brand’s reputation can be long-lasting. That’s why Spore.Bio, a Paris-based deeptech startup, is trying to reinvent microbiology testing to get ahead of the next PR crisis in the food industry. The company recently secured a $23 million Series A round, a little more than a year after it raised an €8 million pre-se
