The advancement of technology has demonstrated how some vulnerabilities can have a huge negative impact on success in companies, as well as irreparable damage. Network security is an indispensable factor to ensure the protection and confidentiality of information against the main traps found in the digital environment.
To stay active in today's market, the company needs to ensure a safe and reliable information exchange, blocking external threats and infrastructure problems. With the migration of most software and tools to a cloud environment, there was also a need to ensure that this information remains out of reach of unauthorized accesses.
For this reason, network security is a necessity for all businesses, regardless of its size or sector.
Network Security: What is it?
Network security involves a number of processes, strategies, technologies and policies that are designed to protect network traffic and information storage . As well as numerous technological resources aimed at improving the processes and activities performed, tactics are also developed to get around the main barriers used for data integrity.
Network security can increase protection at the edges of the network and within it through layers of safety. As well prepared and educated that their employees are, vulnerabilities end up happening, and the consequences of this can be devastating to a business.
The digital environment is a real field of potential threats that may favor cybercriminals' action and destroy the reliability of a market business . The safety of the corporate network has some indispensable foundations for its proper functioning:
- Creation of a prevention culture;
- Investment in security resources;
- Increased protection layers;
- Establishment of access levels according to the user type;
- Periodic update of all systems and tools used by the company.
The 4 types of network security
As we have seen earlier, network security is critical for the company to remain far from the main cyber problems and threats that are recurring today. Through the policies and resources implemented to increase their safety, the IT sector can avoid unauthorized access, virus contamination and malware, cyber attacks, interruption of activities, and more.
The objective of network security is to bring more protection to the data and systems used by the business , being separated into four types:
1- Firewall, antivirus and antimalware
Firewall a security feature that creates a protective barrier on systems and networks, allowing traffic control and monitoring based on pre-established rules . This way, it can block unauthorized accesses and contribute to filtering data packages. Antivirus and antimalware are tools used to detect, block and remove major digital threats , helping to keep the network protected.
2- Cryptography
In summary, encryption makes data unreadable for unauthorized persons. This is possible by coding information by protecting and maintaining the confidentiality of this information during your network traffic. Thanks to this technology, only authorized users can decipher this data.
3- VPN: Virtual Private Network
Through VPN it is possible to establish an encrypted and safer connection between devices and the network. This feature is widely used mainly by remote or home-office employees, ensuring that employees can access resources and internal data from the company's network more safely.
4- DNS Firewall
DNS Firewall is a network security solution that protects against cyber threats. Acting as a defense barrier, he filters and blocks malicious traffic based on DNS queries . This technology identifies and prevents communication with suspicious or known domains for hosting malware or phishing. By adding an additional protection layer, DNS Firewall strengthens network security and helps keep safe systems and data against unwanted attacks.
Find out how network vulnerabilities can affect business continuity
A network security plan involves much more than just using protection tools. It is necessary to establish a complete policy focused on the security and confidentiality of data stored by the business.
This means that even if the company develops an action plan aimed at dealing with possible eventualities, damage caused by safety problems can have short, medium and long term impacts . The image of a business before its consumers and the market can be permanently impaired because of such incidents.
Some cyber attacks are aimed at unavailability of services (such as DDOS attack ), and depending on the duration of this type of attack, the company may have a major financial impact . Although this type of action can be circumvented with the necessary measures, this unavailability can impair market share and make consumers lose confidence in the brand.
Data leakage is also one of the biggest problems faced by today's business. We can see companies of all sizes and segments suffer such attacks and harm considerably. Business that had their data leaked end up being seen with bad eyes by consumers , as the data entrusted to this company does not receive proper protection.
We see a moment of full digital expansion, and business needs to be able to deal with this type of incident to reduce its impact and not to bring losses to its consumers and partners. For this reason, network security is critical to the company's growth and the maintenance of its space in the face of competition.

There is no longer a target audience where cybercriminals direct attacks, which made all companies need to invest in safety measures. What was once an exclusive problem with large corporations has now become an even broader threat that can reach business of all kinds.
must invest in technologies and strategies to protect their data and information . This is because attacks that violate the digital security of companies are increasingly frequent and there are many risks to protect confidential data.
In addition to the leakage of data , which is one of the biggest problems faced today, there are other threats that can also cause numerous damage to the corporation. Ransomware attacks are also victimizing small and medium -sized companies, leading to the loss of their information, unavailability of services and financial losses.
We know that smaller companies need to worry about the size of security investments. It is essential to find a tool that helps maintain security without causing a big financial blow to the organization's coffers.

Importance of network security for companies' growth
Establishing a network security policy within companies is essential to ensure substantial and solid growth. This policy will help protect company data from the main attacks that happen in the digital environment , ensuring not only the confidentiality of this information, but also the reputation of the business.
It is virtually impossible to find a company today that does not depend on much on the internet tools, which makes these businesses face many challenges. Companies need to involve their workers in a digital protection mindset, as well as ensure that the best tools are used to increase business safety.
