So why do you need a Cloud Firewall?

Reason 1: to prevent data leaks

Network segmentation is vital in network access control. Without network segmentation, data leaks can occur more easily.

Not all network members need full access to all company resources. Confusion over what is confidential in different departments can lead to accidental leaks.

Network segmentation is one of the network access control methods and a primary goal of Cloud Firewalls. Network segmentation is when a network is divided into designated areas with specific access permissions. This strategy helps limit access to sensitive data to only those who need it.

Firewall segmentation

NordLayer’s Cloud Firewall offers straightforward controls for setting up detailed network segmentation. Cloud Firewall allows organizations to establish precise network access permissions. You can grant exclusive access to select resources for certain individuals or groups and restrict access for others when needed. The system can also create rules for specific team members, not just for departments or teams.

A Cloud Firewall is valuable in the fight against data breaches as it helps mitigate risks and contain potential damage.

  1. Using a Cloud Firewall reduces the likelihood of a security breach. It acts as a barrier that shields your network from external threats.

  2. Network segmentation, facilitated by Cloud Firewall, prevents lateral movement within the network. This means employees inadvertently leaking data from inside is less likely.

  3. If a breach occurs, the intruder gains access to only a specific network segment. The Cloud Firewall's segmentation limits their reach.

In summary, Cloud Firewall simplifies setting and updating access rules. It allows designated team members specific access to sensitive data, enhancing security. Cloud Firewall is an easy-to-use tool for network segmentation, a vital part of network access control.

Reason 2: to achieve compliance 

There's a wide array of important compliance standards and regulations that focus on network access rights control. Let's look at some examples: 

  1. NIS2—a new EU directive aiming to enhance the Network and Information Systems (NIS) Directive of 2016;

  2. PCI DSS—an international standard which safeguards online payment security; 

  3. ISO 27001—an international standard for IT security management; 

  4. HIPAA—a US federal law focusing on health data protection. 

While not all are mandatory yet, they set high cybersecurity measures.

Complying with high cybersecurity standards is becoming vital for building trust and credibility in businesses. Each one requires robust network access control solutions. A Cloud Firewall is an effective tool to meet these requirements.

In 2024, the NIS2 Directive will be a significant topic as this legislative act will become mandatory later in the year. It applies to various EU industries, requiring a consistent approach to cybersecurity. 

The amplified impact of the NIS2 Directive

NIS2, PCI DSS, ISO 27001, and HIPAA have a strong focus on ensuring safe data transfer and network protection. To adhere to these frameworks, businesses need strong network controls for data protection and secure communication. 

The role of Cloud Firewall in compliance

NordLayer’s Cloud Firewall aids businesses in meeting compliance requirements like those of NIS2 as it helps achieve network segmentation more easily. While not a mandatory requirement for compliance, Cloud Firewall is a versatile and user-friendly solution.

As compliance with the NIS2 Directive becomes crucial for EU businesses, a dependable tool such as Cloud Firewall proves valuable. It ensures controlled network access and enhances data safety. Cloud Firewall is ideal for businesses seeking to adhere to various compliance standards, offering easy use and regular updates.

Proactively implementing a Cloud Firewall before the enforcement of directives like NIS2 is a strategic move. It helps businesses to achieve the necessary network segmentation and prepare for upcoming compliance obligations.

Reason 3: to implement security strategy by best practices

Professionals often turn to established frameworks and checklists when developing a strong network security strategy. These guidelines are critical in shaping and expanding network defense strategies. Implementing network access control measures is a key step in any network security framework. NordLayer’s Cloud Firewall is an effective tool for this purpose.

Popular frameworks guiding network security strategy include SSE and Center for Internet Security (CIS) Controls v8. Both frameworks feature components that focus on network access control, where Cloud Firewall serves as a practical solution.

The SSE framework, introduced by Gartner, merges various network security solutions into a unified cloud service. This framework helps businesses protect their data, resources, and users. SSE includes elements like FWaaS, CASB, SWG, and ZTNA, enabling businesses to counter online threats effectively. In SSE, NordLayer’s Cloud Firewall enhances security and improves threat response.


CIS v8, another well-known cybersecurity framework, features Access Control Lists (ACLs) as one of the key components. ACLs are lists that specify which users can access certain network resources. NordLayer’s Cloud Firewall operates as required for ACLs in CIS v8, managing access to different areas of the network. This is essential for complying with CIS v8 and protecting the network from unauthorized access.

SSE and CIS v8 frameworks are just two examples. Cloud Firewall is adaptable to many other security frameworks and aids in the cybersecurity maturity of an organization. Using a Cloud Firewall aligns with top framework recommendations, offering stronger protection against modern cyber threats and enhancing an organization’s security stance.

Reason 4: to easily unify security across hybrid infrastructures

Many businesses use complex infrastructure systems. These often consist of cloud, on-premise infrastructures, and several remote physical sites. Managing and securing hybrid cloud infrastructures is possible but challenging.

Holistic security for hybrid infrastructures

A Cloud Firewall simplifies the management of these systems. It provides a straightforward, transparent, and potentially cost-saving method for handling complex infrastructures. Saving time in management is one of its major advantages. The Cloud Firewall is beneficial for security and improving operational efficiency in managing these systems.

Businesses with hybrid infrastructures, especially those with multiple physical locations and extensive cloud systems, require a holistic approach. A Cloud Firewall serves this need effectively. It integrates well with different infrastructure components and allows for management from a single point—a browser tab.

The Cloud Firewall offers a unified defense system that meets the varied needs of modern business infrastructures. It efficiently combines cloud and physical network elements and provides detailed control over both. 

This unified approach is convenient for businesses and ensures consistent security policies across various environments. It encompasses both cloud services and on-site data storage and simplifies protection and administration.

Reason 5: to enable and ensure safety in the hybrid work model

The move away from a solely on-site work model is permanent. Employees now prefer options like working from home, working from anywhere, business trips, and workations. 

CEOs may easily accept these flexible models, but the IT department faces a bigger task. They must not only enable remote work but also ensure its security. This change in the work model brings new risks and requires stronger security measures.

Security teams seek solutions suitable for the hybrid work environment that also gives them peace of mind. They need tools that enable and protect remote workers. A Cloud Firewall is an effective solution for both these needs.

Cloud Firewalls work independently of location. They provide equal access to network resources for employees, whether they are abroad or in the office. 

Uniform access is essential for maintaining high productivity and collaboration, especially in widespread teams. Cloud Firewall is very helpful for international companies or those with staff who travel often.
