A firewall is a security device that controls the flow of data on a network . With it, you can filter traffic, configuring what should pass through and what should be discarded. This device works based on a pre-established security policy with web content filtering , aimed at ensuring greater cybersecurity.
And DNS is a system used to provide a more secure environment by translating domain names to IP. As suggested by the acronym DNS – Domain Name System – domain name system.
The DNS Firewall, or DNS filter, allows you to apply an access policy on top of the DNS layer of the network by applying a filter of queries that can or cannot be performed. This filtering is done in a predictive manner and allows access attempts to be blocked in advance, before the exchange of information is carried out.
WEB content filter
A web content filter is a tool used to control access to certain types of content within a network or business system. This filter allows the configuration of rules and restrictions, according to business demand and the need to protect information.
In this way, the Web content filter can be used to block access to content considered malicious or inappropriate and also blocks possible intrusions from malicious devices or websites. Over the years, numerous strategies have been developed to penetrate systems and cause problems for companies, such as malware , DDoS attacks , ransomware attacks and data leaks .
Understand how data leaks can cause great damage to your organization:
Through the help of the web content filter, the company is able to keep only the content that is truly necessary for its operation accessible. And block access to websites that may cause some type of damage to the data and information stored.
For this reason, this tool has been increasingly used to ensure more assertive control of companies' internet access controls.
Web content filter rules must be established understanding the real access needs within the company. Depending on the nature of access, rules may be implemented to block specific content , such as social networks, pornography sites, entertainment pages, online stores, and much more.
MSP: Protect your users from cyberattacks
One of the biggest prerequisites presented by current users is data protection. When we talk about the internet used by companies, the LGPD brought essential paradigms that must be adopted to avoid the loss and diversion of information stored by the business.
Data leakage represents one of the biggest dangers for modern companies. This is because, in addition to causing countless financial losses, this leak can have a huge impact on the company's image in the market and its consumers.
MSPs have been showing substantial growth in the sector, causing the competitiveness between this type of service to increase considerably. To stand out in the market, IT service outsourcing companies need to ensure that their resources and tools are delivering all the protection that consumers need.
For this reason, network security is one of the most important points when it comes to IT services. The meteoric increase in the number of cyber attacks that companies in all sectors have suffered in recent years has demonstrated that security is a key issue regardless of the size or segment of your organization.
Cyber attacks can cause countless losses and make your company suffer penalties imposed by the LGPD. Therefore, having the right tools to increase security and provide more protection for consumers has become essential.
Increase team productivity with web content filter
As we saw previously, web content filtering is a very important tool for businesses that want to ensure greater security and protection for data handled and stored by a company. What many people don't know is that this valuable resource can contribute to increasing the productivity of your employees.
Undue access during working hours can cause your employees to end up wasting considerable time on activities that are unrelated to the company's needs and strategies. An example of this is access to social networks , betting sites, entertainment pages, gaming and streaming platforms, etc.
Therefore, blocking this type of access will help your team stay focused on what is really important for the business and ensure that your company delivers more profitability and growth.
Controlling abusive use of social media during working hours
The popularization of social networks has meant that users of all types have started to use these tools frequently. Access to social networks during working hours can harm the company's strategy and expose confidential information to cyber threats.
Often, even implementing an Internet Access Policy that provides all the information necessary to educate employees, the company still suffers from improper access. Although this policy provides the necessary data, some employees may maintain this type of behavior and cause several losses to the business.
Due to this type of behavior, having complete tools to control the abusive use of social networks during working hours has become an indispensable measure. Although the internet is necessary to carry out fundamental business tasks, it can also become a real productivity and cybersecurity trap.
Therefore, it is very important that your employees understand the need for control to maintain security within the digital environment and prevent the company from being harmed due to improper access to this type of website . Each person must understand their role within the organization and adapt to the organization's expectations.
Block adult, pornography and violence content
Representing an even greater risk than access to social networks and other types of websites, access to adult, pornography and violence content must also be controlled. Although it may seem obvious to many people, this type of access is still carried out during working hours. Not only damaging productivity, but also causing technical problems and exposing company information to access by cybercriminals.
Block adult, pornography and violence content This type of inappropriate content must also be blocked by the organization to ensure greater security and avoid problems caused by malicious and dangerous websites that can be found in the digital environment. Most pornography websites were developed to not only offer this type of content but also create points of vulnerability that facilitate unauthorized access to confidential information.
Your company's strategy must take into account the problems caused by this type of access and blocking must be a priority. An example of this is the misleading advertising that is implemented on pages with adult content and the exchange of information that is carried out through registration or creation of an account.
