Next Generation Firewalls

Every organization, be it small, large, or public, has to protect its data. Traditional network protection often fails today when facing advanced cyber-attacks. A new, holistic approach to data security has to be applied. Already the third generation of firewall technology, it combines a traditional operation filtering with other functions.

In today’s world of mobile devices and cloud, where data is virtually everywhere, employees are accessing public websites and surfing social networks on daily basis and their mailboxes are full of potentially malicious e-mails. It is quite easy to penetrate deep into an organization, so deep, that the hackers dared not even to dream about it just few years ago. Well, it is the reality now, and that is why we have the next generation firewall (NGFW), which can recognize an attack on your network and stop it immediately. They can identify even totally new threats and will protect your servers, endpoints, as well as the whole network perimeter.


By implementing the next generation firewall to your company network, you also become compliant with some of the GDPR and the so-called cyber law provisions. Only such complex environment will really make sure that your company network or data centre is secured against malicious attacks, potentially resulting in the theft of your intellectual property, personal data, or in the loss of data from your data centre hosting dozens of clients.

If you have had an inkling for some time that there might be holes in your existing solution, please talk to us. ComSource is working with top NGFW suppliers. If you are a company or a corporation, you will surely find a solution from Forcepoint, the top provider of corporate communication security, to be to your liking. If you run a data centre or provide data services, a Juniper solution is the right one for you. Both products have the required certifications.

However, it is possible that after analysing your needs, a totally different solution will be suitable for you. Our experts will analyse your company, recommend the right one and will take care of the potential implementation as well as know-how transfer.
