NIL Secure - Network Security Assessment

Are you aware of your network vulnerability?


Technology has transformed the way we all do business. Today’s companies and organizations enjoy huge opportunities for improving productivity and reaping the benefits of data sharing with customers, suppliers and business partners. Information and communication systems have become open, flexible, responsive and global, but without proper management this same technology brings many security risks. The key challenge is data security – safeguarding the company’s information assets. Because of its impact, network security has become a critical success factor for businesses. NIL professional services can help you to reduce threats and prevent intrusions with regular security assessments of your network infrastructure.

What is the purpose of the NIL Secure service?

The purpose of the network security assessments with the NIL Secure service is to detect network weaknesses and to define the level of risk that an organization's business process is exposed to, as well as to identify those areas that need improvement from the aspect of security.

The result of the NIL Secure service is a set of recommendations for network improvements that will reduce vulnerability and lower the risk.

NIL Secure checks the efficiency of the implementation of an organization's security policy and assesses the compliance of the actual implementation of network security measures with the documented security policy. For those cases where an organization has no security policy defined, the NIL Secure service leads to recommendations to introduce security mechanisms based on the current best practices and standards, such as ISO 27001.



Network security assessment with the NIL Secure is not a penetration test where deficiencies in the network infrastructure are evaluated by simulating attacks. This method is not accurate enough as it does not allow insight into detailed network parameters (device settings, data flows, etc.) that can only expose even well covered security deficiencies. The penetration tests may also interrupt the business processes of organizations, which is why they are not recommended as the basic way of security checkups. The NIL Secure service is based on a detailed analysis of network configuration and characteristics of all devices included in the assessment. Controlled simulations of attacks are carried out only when explicitly requested by the client, typically as a proof of the detected vulnerability.

The NIL Secure offerings

The NIL Secure service may include the following offerings:

Network Infrastructure Security Assessment (LAN, WAN)
The key component within this service is security assessment of the internal enterprise network infrastructure security assessment that supports key business processes. NIL Secure detects network devices (routers and switches) vulnerabilities, as well as their network and security services (routing protocols, anti-spoofing services). The assessment includes both the network access layer, where endpoints connect to the network, as well as the distribution and core layers of the internal network.

Firewall Security Assessment
The enterprise perimeter is typically connected to external networks, such as public networks or networks of business partners by using firewall systems. NIL Secure analyzes the quality of the firewall system implementation, the firewall system resistance, granularity of separation, firewall rule correctness, and management.

VPN Security Assessment
Virtual private network (VPN) connections have a number of possible vulnerabilities due to the complexity of their settings, key management complexity, and exposure to public networks. NIL Secure analyzes the quality of cryptographic settings (algorithm choice, key length, authentication mechanisms, etc.) and the quality of access control between public and private networks over the VPN device. The service supports both IPsec and SSL VPN technologies.

Wireless LAN Security Assessment
Wireless LANs provide significant benefits, but expose an organization to a series of possible threats that can be mounted across physical perimeter boundaries. NIL Secure analyzes the quality security settings for WLAN devices (and associated infrastructure, such as AAA servers), the quality of cryptographic settings (algorithm choice, key length, authentication mechanisms, etc.), and identifies the presence of unauthorized WLAN endpoints.

IP Telephony Security Assessment
Enterprise IP telephony in its default setup is often vulnerable to various network threats, such as signaling controller compromise, call interception, and theft of services. NIL Secure service detects vulnerabilities in the network infrastructure that supports IP Telephony services, and vulnerabilities in IP Telephony endpoints and applications, such as IP phones, signaling controllers, gateways, etc.

What is the result of the NIL Secure service?

The result of the NIL Secure service is a report on the network security posture and includes recommendations for network infrastructure security improvements. The report also includes a priority list of suggestions how to decrease risks, adapted to the environment and special needs of the organization.

The NIL Secure advantages

With the NIL Secure service you gain the following key advantages:

  • proactive prevention of business damage as a result of preventive fixes of errors
  • increased availability and stability of the network functioning
  • integral insight into the network functionality and current condition of key business processes
  • consulting about strategic decisions for network improvements and faster investment on return
