Data protection is the new big issue in the modern world. In recent times, we’ve seen so many big companies losing tons of data to trespassers. We have recent examples of companies like Marriot and British Airways who announced their data loss to hackers. If you’re an owner of a small or medium business, you might be thinking that you’re safe because these hackers only go after the big players.

Well, that’s where you’re wrong. And you’re not the only one thinking that way. According to the 2019 MidYear QuickView Data Breach Report, 4.1 billion records were compromised by 3800 breaches of which 8 breaches alone exposed 3.2 billion records. These are astonishing figures indicating the fact that around 80% of the records exposed belonged to 8 big companies. However, it certainly does not mean that small or medium businesses were not affected at all.

In fact, “The majority of breaches reported this year had a moderate to low severity score”, exposing 10000 or fewer records, according to the report. Therefore, like you, there were other owners as well who thought that their business was too small to be on the radar of hackers and look at how they paid the price.

These are the companies that are easy targets for the trespassers as they have no proper security system in place. It’s the big breaches that make the headlines but small businesses suffer daily to fill the pockets of the hackers.

Hence, whether your company is big or small, you need to have a security system in place to keep your data safe. You might think of it as a cost, but consider it as an investment if your data is important for you. To strengthen your security system, you need to avail yourself service of a good security testing company. The job of a security testing company is to detect vulnerabilities and flaws in your system and make sure that your system is not exploited and remains functional. To save costs, you need to involve software testing in the early development stage.

One of the main ways, for example, a security testing company will test your system is by ethical hacking where the tester will play the role of the attacker and will simulate an attack on your system to determine its vulnerability. This is also known as penetration testing.

Now that we’ve told you about the importance of security testing, you need to know which the top companies are providing the best security services. Following is the list of our picks for Top Security Testing Companies:
