How we go deeper to protect you from new threats

Read our whitepaper about F-Secure DeepGuard, our proactive protection against new and emerging threats. Read it here.

You may know that F-Secure won the Best Protection Award – twice in a row. But if you’ve ever wondered about how we actually go about protecting our customers from malware, this post is for you. We do it by going deeper. Let me explain.

Traditional antivirus software looks at the outward characteristics of files to see if the characteristics match those of previously seen malware files. If they match, the antivirus program knows to block the file.

For this system to work, antivirus labs need to have a sample of the malware file in order to analyze its characteristics so they know exactly what they need to block.

This is a very effective method for blocking most malware seen to date, and this is how F-Secure protects you from existing malware we already know about.

Of course, it takes time for antivirus labs to receive a malware sample and analyze it so we can effectively block it. That means brand new malware created just in the past few days or weeks that we haven’t yet had a chance to analyze, can get past traditional scanning systems.

Complicating the issue, cybercriminals who create malware nowadays are very clever at avoiding detection by antivirus programs. One way they do this is by creating new, different variants of their malware. These variants are still the same malware at the core, but they appear new and different on the outside. Like a criminal who dresses in disguise to avoid being recognized, the malware file is disguised to avoid detection by antivirus software. There are automated malware creation kits that do this for the cybercriminals, making it easy to spit out thousands of new variants.

To be able to protect from brand new malware, then, and to protect from all the new variants of existing malware, it is crucial for F-Secure’s software to be able to detect a malware file even before our Labs have ever received a sample of it.

So how do we block malware strains we’ve never seen? We examine not just a file’s outward characteristics, but we also monitor its behavior for suspicious activity. Like I said, malware can change in appearance and characteristics. But one thing never changes: Malware always does malicious things. So if we’re not sure if a file is malicious or not, we watch to see how the program behaves.

We call our behavioral analysis technology DeepGuard. DeepGuard observes a program’s behavior and prevents potentially harmful actions from successfully completing. This way, we can block even brand new malware files that haven’t yet been analyzed. And we can stop malicious files that are disguised as something else.

When the user opens a file, any file, DeepGuard instantaneously checks for suspicious behavior, and if it finds something, it will block the program from launching. Since some malware hide their malicious behavior until after the program launches, DeepGuard still continues monitoring programs while they are running, watching for and blocking suspicious actions.

DeepGuard is a feature of F-Secure’s products, working in tandem with our other protection layers (browsing protection, traditional signature scanning, file reputation analysis, and prevalence rate checking) to provide the very best protection. Our newest version, DeepGuard 5 with exploit protection, has already been rolled out, so customers with the latest versions of F-Secure products are already benefiting from the latest technology.

And that’s how we protect you.

Why press freedom matters and how tech can help

World Press Freedom Day: Why it Matters and How Tech Can Help

Finland is home to the freest news media in the world, according to Reporters Without Borders. It's fitting, then, that the annual UNESCO World Press Freedom Day conference will be held in Helsinki this year, May 2-4. Freedom of information is a topic that's close to our heart. We were fighting for digital freedom before it was cool - yes, before Edward Snowden. A free press is foundational to a free and open society. A free press keeps leaders and authorities accountable, informs the citizenry about what's happening in their society, and gives a voice to those who wouldn't otherwise have one. Journalists shed light on issues the powers that be would much rather be left in the dark. They ask the tough questions. They tell stories that need to be told. In a nutshell, they provide all of us with the info we need to make the best decisions about our lives, our communities, our societies and our governments, as the American Press Institute puts it. That's a pretty important purpose. But it can also be a dangerous one. Journalists working on controversial stories are often subject to intimidation and harassment, and sometimes imprisonment. Sometimes doing their job means risking their lives. According to the Committee to Protect Journalists, 1189 journalists have been killed worldwide in work-related situations since 1992, when they began counting. 786 of those were murdered. Freedom of the press and digital technology are inextricably intertwined. Journalists' tools and means of communication are digital - so to protect themselves, their stories and their sources, they also need digital tools that enable them to work in privacy. Encrypted email and messaging apps. Secure, private file storage. A password manager to protect their accounts. A VPN to hide their Internet traffic and to access the content they need while they're on assignment abroad. F-Secure at World Press Freedom Day It's because press freedom and technology are so intertwined that it's our honor to participate in this year's World Press Freedom Day conference. Here's how we'll be participating in the program: Mikko Hypponen, Chief Research Officer at F-Secure, will keynote about protecting your rights. Tuesday May 3, 14:00 to 15:45 Erka Koivunen, our Cyber Security Advisor, will participate in a pop-up panel debate on digital security and freedom of speech in practice. Tuesday May 3, 15:45 – 16:15 Sean Sullivan, our Security Advisor, will be on hand to answer journalists' questions about opsec tools and tips. One of our lab researchers, Daavid, will be inspecting visitors' mobile devices for malware. We'll feature our VPN, Freedome.   Check out our Twitter feed on May 3 for livestream of Mikko's and Erka's stage time.                 Banner photo: Getty Images

Internal startups are a way for big companies to innovate and adapt.

Why an Internal Startup Could Be Companies’ New Recipe for Success

AirBNB. Uber. These are but two examples of disruptive startups that are popping up to challenge big organizations' legacy mindsets and business models. Digitalization has completely shaken the world, and companies have two options: adapt to stay in the game, or be left behind in a cloud of dust. But it's hard to turn a big ship around. That's why F-Secure's Harri Kiljander, Janne Jarvinen and Marko Komssi believe that a great way for companies to accelerate innovation is to bring the startup model in-house. They've collaborated with peers from other organizations in a new ebook, The Cookbook for Successful Internal Startups. The book is a practical guide to establishing and running an internal startup. An internal startup, they say, is a great route to cheaper innovation execution and faster time to market. And the three have experience to draw on: F-Secure has developed its VPN product, Freedome, its password manager, Key, and its smart home security device, Sense, all as internal startups. The book pulls together F-Secure's learnings as well as the learnings of other companies who use the model. I caught up with Harri, Janne and Marko to talk about the internal startup scene. What is your definition of a startup? Harri: A startup is an organization that is established to build a new product or a new service under a significant uncertainty. Trying to do something new that doesn't exist yet, and constrained by a lack of established processes or budgets or resources. Janne: To me, a startup is the means to build something new and disruptive, and build it as fast as possible, with the intention of scaling as quickly as possible. You're not trying to make something that just a few people can do for a living, but you're trying to build up a big business quickly from something new. Marko: A startup is an entity that is searching for a scalable, profitable business model. It differs from a company in that a company has already found its business model. Why do you want to encourage big companies to form internal startups? Harri: Big companies are really good at doing old things. An internal startup is great way to introduce new ways of working and to try developing and launching new and better products and services. Janne: All companies want to explore new areas, but in the established organization it's difficult to start something new. With an internal startup, you don't worry about the existing organizational structures. From a company perspective, because the startup is not embedded into the larger organization, it's easier to handle and it's easier to see whether it's producing results. It also gives employees the chance to be involved in something new. How has the internal startup model been beneficial for F-Secure products Freedome and Key? Harri: One of the key elements has been the rapid development and feedback cycle - the classic cycle of build, measure, learn. Build something, release it, gather feedback from users and markets, and then adjust your product, pricing, channels, etc. The more rapid you can make this cycle, the higher the likelihood of being able to generate success. Janne: We built Freedome and Key much faster as internal startups than we would have done in the traditional way. The global launch took place just nine months after the idea, and that's extremely fast. Marko: Freedome was incubated in strategic unit, not the business unit. It had more freedom as it was able to work independently, without being under any existing business pressure. What is the biggest advantage an internal startup has over an independent startup? Harri: The ability to access the big company resources, including free labor and expertise. In a big company there are a lot of experienced people who yes, may be stuck with old ways of working, but they still have lots of experience and know about doing business. Marko: Access to the company lawyers, marketing competence, PR, company name brand, social media channels with established followings, etc. A startup has to pay for everything or get the competence somehow, whereas a big company has it in house. And vice versa, what is the biggest advantage an independent startup has over an internal startup? Janne: It's not constrained by a company's mindset and objectives, so it has more freedom. However, once an independent startup gets financing, the people writing the checks will start to want some control anyway, so in that sense it's not so different from an internal startup. Marko: The feeling of ownership. The independent startup team really feels that they own the idea. With an internal startup you somehow still feel that you are a company employee first. So ownership is weaker in an internal startup and that has an impact. What do you hope people take away from the startup cookbook? Harri: I hope people get a spark of courage to establish this kind of exercise in their own established organization. If they're not sure how to go about it, they are welcome to contact the writers of the book and we might be able to help them. Even big organizations can do things fast if they follow the recipes or principles we outline in the book. Janne: I hope people in large organizations see that they can explore new areas using this model. Our goal is to really help people learn from other companies' experiences so that they don't have to learn everything on their own. Read The Cookbook for Successful Internal Startups The Cookbook for Successful Internal Startups was created by the industrial organizations and research partners of Digile’s Need 4 Speed program. F-Secure is the driver company of N4S and Janne Järvinen leads the N4S consortium. Harri Kiljander is Director of Privacy Protection, Janne Jarvinen is Director of External R&D Collaboration, and Marko Komssi is Senior Manager, External R&D Collaboration at F-Secure.
