ZTNA – Zero Trust Network Architecture is also known as software defined perimeter (SDP). It includes the solutions that are implemented by an organization to give its employees access to only those resources that are used by them. This reduces the risk of a possible cyber attack or data leakage issue for the organization.

The ZTNA solution identifies the authenticity of the user and links the identity to their collection of roles defined within the organization.

The access controls within the ZTNA solution ensure that all traffic passing through the organization’s network go through the ZTNA solution for enhanced security.

With the flexible working environment being introduced post-pandemic, it has become inevitable for organizations to choose an approach that offers scalability and agility to secure the distributed workforce. 

Benefits of ZTNA implementation within organizations

The Zero Trust Network Access solution can be implemented within the organization through a set of use cases that are specific to every individual organization.

These use cases are implemented within the organization based on their functionality and network usage.

  • Secure Remote Access: VPNs are used by most of the organizations to support a remote workforce. The major drawback of VPNs is that they provide access to the complete network to an authenticated user. Through the effective use of ZTNA solutions the accessibility of remote workers can be restricted to only a few functionalities of the network that are necessary for accomplishing their jobs.
  • Secure Cloud Access : The use of a cloud infrastructure is increasing as many enterprises have realized the multiple benefits of cloud storage solutions. It is necessary for organizations to limit the access of cloud-based resources for a secure and intrusion free network.

Reduce the risk of a possible intrusion

The most common goal of intrusion for cybercriminals is through a compromised account. A user account that has been compromised allows an attacker to move through the organization network and access multiple resources thereby leading to potential damages. Implementation of ZTNA helps to minimize the intruder’s access level and reduce the amount of damage caused to the resources. 

Ways to implement ZTNA within an organization

ZTNA solution can be implemented within an organization through the following ways:

  • Gateway Integration: ZTNA can be implemented within the network as part of the network gateway access policy. The traffic entering the network is filtered based on the permissions and the access control policies. Any user attempting to access the network needs to have authentication for using the various resources within the organization.
  • Secure SD-WAN: SD-WAN within an organization is used to implement optimized networking access within the organizational WAN. Secure SD-WAN is used to integrate a secure stack into each appliance within the network. Implementation of ZTNA into this SD-WAN stack helps to provide a centralized access management within the organization.
  • Secure Access Service Edge (SASE): The SASE functionality includes making the SD-WAN functionality available as a virtual appliance in the cloud. It helps organizations to maximize both network efficiency and security, including ZTNA functionality.


Implementing ZTNA within an organization helps reduce the risk of cyberattacks. Allowing employees with limited access to resources based on their roles and responsibilities helps reduce the damage caused by potential intruders or a malicious insider.

Incident response is a critical component of any organization’s security strategy. It encompasses a set of policies and procedures that are put in place to identify, contain, and eliminate cyber-attacks. The goal is to quickly identify the root cause of the attack and prevent it from causing further damage, minimize the impact, and prevent any future attacks.

The incident response process involves several phases, each of which is essential to the overall success of the strategy. These phases include preparation, identification, containment, eradication, and recovery.

Let us know in detail about the various phases of incident response.

  • Preparation: This phase involves training the employees within an organization about the various security measures they need to take while accessing sensitive data. It is necessary for organizations to have proper planning to secure the data and various systems.
    A systematic review of the various security implementations should be conducted regularly to evaluate the incident response plan.
    It is necessary to check the availability of the various resources needed to implement an incident response plan including hardware and software resources. The incident response plan includes proper training and execution of the security procedures.
    Ensure employees within the organization have awareness of the possible threats a system can have and what are the best practices to avoid such risks.
  • Identification: This phase of incident response involves identifying whether a breach occurred within the network. If actually a breach is detected, then the primary cause of the breach should be analyzed. The system that has been compromised should be identified and the extent to which the system has been compromised should also be analysed.
    It should be identified whether the breach is affecting the operations. The source of the event must be discovered to stop further damage to the systems.
  • Containment: Organizations often try to delete the breach upon its identification. This may sometimes lead to destroying crucial information causing major damage in the long run.
    Hence it is advised that the breach should first be contained to stop it from further spreading. Identify the devices that are affected by it and disconnect them from the network. Analyze the amount of damage caused and start implementing strategies to overcome the situation. Having a long-term and short-term containment strategy to handle the procedure is essential to restore business operations.
    In case the system updates are not done it is advised to update and patch them to remove any malware. After the updates changing the passwords with stronger ones and rechecking the administrative credentials keeps the systems safe for future use.
  • Eradication: After identifying the cause of the breach and containing it from causing further damage it is necessary to remove it from the systems. The process of eradication involves removal of malware and rectifying security issues. It is essential to detect if any malware is still present in the systems as it may lead to data loss.
    After ensuring that malware is completely removed from the system it should be updated, hardened, and patches applied.
  • Recovery: However fast the containment is implemented there is some loss of data and damage caused to the systems during a breach. It is, therefore, necessary to implement the restoring the affected systems and devices for quick resuming of the business services.
    Installing tools that will ensure safety from such attacks is necessary. Implementing a robust backup and recovery system also helps in restoring the systems.
  • Lessons Learned: After restoring the systems and following the safety precautions it is necessary to hold a reliable incident response action policy with all the members of the team. The team should discuss what the actual cause of the breach was and how it could have been averted. Rectify the loopholes in the incident response plan and identify the strong points that worked in favor. This analysis will help businesses to strengthen the network system from future attacks.


Incident Response system is a necessary plan of action that every organization needs to follow for keeping their systems safe from possible breaches.

Implementing a reliable Incident Response plan relying on a third-party organization helps in making the whole process a hassle-free procedure. The engineers with the organization have years of experience in handling such difficult situations and have in-depth knowledge of rectifying the issue with minimum possible damage caused to systems.

We at Prutech offer a robust and well-planned Incident Response system that has helped several organizations to get back to business with less downtime and less amount of data loss.

According to research conducted by Hiscox, 7 out of 10 small businesses have not taken basic steps to safeguard themselves from cybercrime. Taking essential cybersecurity measures, like establishing a network firewall, is incredibly essential for businesses small and large. Firewalls stop malicious actors and hackers from getting access to your company’s sensitive data and protect your organization from cyber threats, like malware and virus.

What is a Network Firewall Security?

A firewall is a software or hardware network security system designed to protect your network from malicious, unwanted approaches made by hackers. A firewall safeguards your network from external threats and provides end-to-end security by carefully analyzing information getting in and out of your network.

Here are 9 reasons why every business should have a network firewall.

1. Safeguards Your Company Against Hackers

A network firewall protects company data by sending timely alerts whenever there is a breach or an attempt to breach made in your network. There is malicious software that is capable of getting attached to the network’s incoming traffic. Firewall networks are capable of blocking them. Nowadays, cybercriminals get access to a business’s network and system through social engineering.

Cyber hackers and criminals use several tactics and tricks to trap employees that can provide hackers with the company’s sensitive information. Employees must be trained about being aware of cyber hacks and the tricks they use. It is important for the company to invest in both – educating employees and a good firewall.

2. Protects Your Company Data In the Cloud

With the increasing quantity of data being created and shared internally in organizations, it is absolutely necessary for businesses to resort to cloud data services. So many businesses are continuously opting to host their data in the cloud instead of their servers.

Though it is a great move financially, it does have a risk and a downside – you are not in control of your data. You have no option but to trust the cloud data service provider you choose for data storage. Having a network firewall and a firewall policy in place minimizes that risk considerably. Firewalls check and re-check every bit of data to make sure no type of malicious code gets into the system.

3. Allows You To Block Access to Certain Websites

While the internet has made the world a global village, it is also home to many unsafe websites. A firewall allows you to block unsafe and suspicious websites that you want to restrict your employees from visiting. This is very useful if you want to restrict your employees from visiting inappropriate sites or those suspicious sites that might consist of malicious downloads while working in your organisation.

For instance, you can choose to block gambling sites, pornographic websites, and social media websites. With a network firewall, you, as an employer, stay in control of what your employees can access when they use the organisation’s computers at work. This is great from the perspective of increasing productivity as well.

4. Helps Secure Network When Being Accessed Remotely

With the novel coronavirus taking over the world and lockdowns being declared in many countries, remote working is now being happily accepted as a part of work culture. So many organizations worldwide had no other option but to rely on remote working. Though it was a partially great thing for both employees and employers, protecting our network when employees are working outside of your internet service provider is much more tricky.

Having a firewall established secures the connection between your remote employees and your company’s server. Moreover, it also blocks unauthorized access and restricts them from accessing the data being shared.

5. Helps In Limiting Bandwidth Usage

Bandwidth usage which is not business-related is another problem businesses have to deal with. When there are fewer people using the internet for lesser things, internet speed is much faster. If fewer people are using it, the data speed that employees can enjoy will be much higher and they will be able to get their work done faster. This proves to be especially true when employees start exploiting the company’s internet for consuming content which is not related to work, like listening to music and watching videos.

A firewall enables you to limit the internet bandwidth amount that is being used for non-work-related things. The firewall does not turn off the internet entirely but lets you limit how much bandwidth can be used for watching videos or looking at pictures, amongst other things. This is how firewalls help in saving bandwidth and reserving faster speeds for only work-related activities solely.

6. It Can Be Used For Providing VPN Services

In the normal internet we use, the data being shared and transmitted across any public network is not secure and may carry malicious software. Network firewalls provide VPN services that don’t just conceal data and information shared between two parties but also act as a point of entry which connects your company’s WAN (Wide Area Network) and LAN (Local Area Network).

VPN (Virtual Private Network) uses coding technology or encryption for the protection of the communication and data shared amongst employees of the organization. A company’s firewall settings can be configured in a way that only specific computers can access the internet. A tunnel can also be used to connect these computers which enables them to communicate over the internet securely.

7. Makes Using New Apps a Safer Experience

One of the main functions of a firewall is to monitor your network tirelessly and block any traffic that has the potential of being a threat to an organization. This function makes integrating new software and applications a much safer experience. Without the presence of a network firewall, new applications downloaded may enter a connection that might compromise your business data and network.

On the other hand, an efficient firewall managed by a network security services provider identifies and flags malicious activity before it happens and causes any harm. When you get a good firewall installed in your organization, you do not have to worry about these things.

8. Helps in Meeting Compliance

Cybersecurity regulations involve complicated legal language. Additionally, compliance regulations also keep updating and upgrading frequently. However, no matter how complicated it is, it is important for every organization to comply with regulations like the PCI security standards and HIPAA Security Rule. A good, updated network firewall doesn’t just protect your network, it also helps your company comply with all the necessary cybersecurity regulations and security standards.

9. Protects Your Company’s Network, Data, & Employees from Malicious Code

Computers run on code, and this code enables people, businesses, and networks around the world to communicate. As fascinating as code is, it also brings some major issues that need to deal with. It brings a lot of unnecessary junk into your computer and networks, uses unnecessary space, and wastes resources.

Additionally, hackers and cybercriminals use code to break into your network and then use more codes to hide spam, viruses, and worms. These malicious codes have the potential of harming your organization by giving hackers access to your valuable data.

With a firewall in place, you rest assured that groundbreaking software is looking after your network 24/7. It also checks each and every single code that comes in and goes out. Moreover, it also reports any attempts that are made to intrude on your server or network incorrectly or illegally.

Firewalls ruthlessly block anything that is out of the ordinary and this protects your network’s systems and the valuable data that resides in it. A firewall is also capable of learning and remembering malicious applications that breached or attempted to breach your network, blocking them, and further protecting your network.

Despite advanced cybersecurity measures, cyber attackers are continually finding new ways to gain access to crucial organizational data. This trend is alarming, and it is essential for enterprises to closely monitor the root cause of any Ransomware attack that has occurred recently. By doing so, they can implement security measures to avoid critical assets from being attacked.

The potential risks of Ransomware to businesses are significant. Not only can it cause financial losses, but it can also damage a company’s reputation and customer trust. Therefore, it is crucial for businesses to take proactive measures to protect their data and prevent Ransomware attacks from happening in the first place.

One way to do this is by investing in robust cybersecurity solutions that can detect and prevent Ransomware attacks. Additionally, businesses should educate their employees on how to identify and avoid potential Ransomware threats. By doing so, they can create a culture of cybersecurity awareness and reduce the risk of Ransomware attacks.

Ransomware attacks cause major losses to businesses. The most impactful of them include:

  • Monetary Loss: Ransomware attackers often demand hefty amounts from businesses. Apart from this, due to inaccessibility to crucial data and files there is a huge loss of revenue. Due to the unavailability of the business resources service availability also affected leading to customer dissatisfaction.
  • Ransom payment: Businesses have to pay amounts varying anything between hundreds and billions of dollars depending upon the size of the organisation. Sometimes there is no guarantee that the data and files are restored or unlocked. Regulatory authorities often discourage companies from paying the Ransomware.
  • Business reputation: Data being the most valuable asset, the onus lies on the organisation to safeguard it. In the event of a Ransomware attack the business reputation gets impacted when the news comes out. Most of the customers become apprehensive of the safety of their data and start doubting the credibility of the organization. In such situations, it becomes a difficult task for organizations to retain clients and customers. 
  • Regulatory fines: In certain instances where sensitive customer data is compromised due to Ransomware attacks businesses have to face regulatory fines and legal issues slapped by customers and clients. It becomes an added burden for the business apart from paying for the Ransomware.


 Ransomware attacks pose a severe threat to businesses, and it is essential for organizations to take proactive measures to protect their data. By investing in robust cybersecurity solutions and educating employees on how to identify and avoid potential threats, businesses can reduce the risk of Ransomware attacks and safeguard their critical assets.
