Network Security

"Network security is like a lock on a door - if it's secure enough, even the owner can't get in!"

"Why worry about vulnerabilities? Just invite the hackers over for tea and let them point out all the weaknesses for you."

Network Security

Network security is the practice of protecting networks, systems, and programs from digital attacks. These attacks are usually aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes. It involves multiple layers of protection, including firewalls, encryption, access control, user authentication, and other security best practices. Network security helps ensure that only authorized users have access to data and resources, and that data is kept secure from malicious actors. Network security also helps protect confidential information from unauthorized disclosure and prevents malicious software from being installed or executed on networks.

Network Security

At digiALERT, we specialize in protecting organizations' computer systems and networks from unauthorized access, use, disclosure, disruption, modification, or destruction. This includes protecting against various types of cyber attacks such as malware, phishing, man-in-the-middle, and other malicious activities. We implement measures to ensure the confidentiality, integrity, and availability of data, applications, and systems.

Our network security solutions include both physical and logical security measures. We provide protection to physical infrastructure of the network, such as routers, switches, and other network devices. Additionally, our logical security measures are in place to protect the data that travels across the network. This includes using firewalls and antivirus software, encrypting data, and implementing authentication mechanisms.

We also use access control mechanisms, such as authentication and authorization, to ensure that only authorized users have access to the network. This helps in preventing unauthorized access to sensitive information. Additionally, we employ intrusion detection and prevention systems to detect and stop malicious activities on the network. Trust us to secure your organization's network, and allow you to focus on your core business operations.

WHY Network Security
WHO NEEDS Network Security

Network security is an essential part of any organization's long-term strategy. It helps to protect data and resources from unauthorized access, malicious attacks, and other security threats. Network security helps to keep data safe from attackers who may try to gain access to a company's sensitive information, such as financial records and customer data. It also helps to protect against malicious software and malicious actors who can try to infiltrate a company's systems.


Network security is needed by everyone who uses a computer or other device connected to the internet. Businesses, governments, and individuals must use network security to protect their data and resources from unauthorized access, malicious attacks, and other security threats.


Businesses need network security to protect their data and resources from malicious actors, unauthorized access, and other security threats. They need to protect their networks from being used as a platform for malicious activities, such as data loss, identity theft, and financial fraud. Additionally, businesses need to protect their networks from malicious actors who can use them to launch distributed denial of service (DDoS) attacks, ransomware attacks, and other malicious activities.

How often is Network Security recommended
When it would be performed

It is recommended to perform network security assessments regularly in order to ensure the security of an organization's network infrastructure. The frequency of these assessments may vary depending on the size and complexity of the network, as well as the level of risk the organization is willing to accept. For example, a small business with a simple network may only need to perform a network security assessment once a year, while a larger organization with a more complex network may need to perform assessments more frequently, such as every quarter.

Additionally, it is important to perform network security assessments after any significant changes to the network, such as adding new hardware or software, or when there have been security breaches or other incidents. Regular assessments can help identify vulnerabilities and potential threats, allowing organizations to implement the necessary security measures to protect against potential attacks. Overall, it is important for organizations to assess their network security regularly in order to maintain the integrity and confidentiality of their data and systems.
