Logical perimeter security

Attacks on corporate networks, resources and users have evolved considerably in recent years and cybercriminals, hackers and other hacktivists have a whole arsenal of tools and techniques to bypass traditional security measures.

The exponential development of information systems, the multiplication of interconnections, the evolution of threats as well as the increase in tools and applications used make security a major issue for companies. Security must be done per application and per user. In addition, intrusion detection, antivirus analysis, URL filtering and content filtering are elements that should not be overlooked in order to maintain an optimal level of security. To combat attacks that increasingly target the security of companies’ IT perimeters, TUNTEC offers solutions to protect your network adapted to the challenges that your company must protect itself from. We provide network security using hardware and software:


Firewall protection

The main role of the firewall is to block unauthorized access, a role which becomes more complex over time due to the appearance of new threats and escape techniques associated with the increase in the volume of data and the diversity of means of access to the company’s information system.

We provide our customers with different firewall deployment modes as needed:

  • Dynamic firewalls: The stateful firewall is the most basic firewall technology. It remembers the state of all network connections passing through it and is still used today to protect networks, instead of traditional access control lists.
  • Intrusion detection: Intrusion detection is offered as a stand-alone solution or as an add-on to a new generation firewall solution. It detects and blocks threats from malicious and risky applications before they reach network devices. It uses real-time threat intelligence coupled with intrusion detection rules.
  • Unified Threat Management: Unified Threat Management (UTM) is a network security solution that offers several security features. UTM functions include: antivirus, anti-spyware, anti-spam, installation of network firewalls, intrusion detection and prevention, content filtering and leakage prevention.

Protection pare-feu nouvelle génération

The firewall is the most strategic component of the perimeter security infrastructure. It monitors all traffic and positions itself in the most efficient location to reinforce security policy.

Unfortunately, traditional firewalls rely on ports and protocols to classify traffic, allowing applications and tech-savvy users to bypass them with ease, by skipping ports, using SSL, sneaking in. through port 80, or using non-standard ports.

The loss of visibility and control puts administrators in a dangerous situation and exposes businesses to network outages, compliance violations, increased operational expenses and possible data loss. The historical approach to restore this visibility and control requires that the “firewall helpers” be deployed individually. Neither of these methods solves these problems due to limited traffic visibility, cumbersome management, and latency in scanning processes.

Restoring visibility and control requires a new approach.

Next Generation Firewall (NGFW): NGFW is part of 3rd generation firewall technologies and combines the capacity of an enterprise firewall system, intrusion prevention system (IPS), control application, URL filtering, VPN, sandboxing and much more.

It requires a new generation of firewalls and it is essential that they are easy to manage and provide complete visibility and security in traditional, private cloud and multi-cloud environments. These firewalls must be integrated into the existing security architecture, which should include an Identity and Access Management (IAM), SIEM and sandboxing program. TUNTEC offers the best firewall protection integrating visionary vendor products in the form of fully or partially managed services. The combination of advanced technology and experienced engineers from TUNTEC guarantees optimum efficiency and the highest level of safety.
