Critical applications are those that are most important to businesses. They largely determine a company’s course, due to their high dependence on them. Critical applications are usually large in size, which means that they can store a large amount of data. Also, they have versatile processing engines that can more easily process large amounts of data. 

 The types of mission-critical applications differ depending on the task they are made to perform. Some of the types are financial applications, medical applications, messaging applications and legacy systems.

Financial applications 

 A very important type of critical application for a company are financial applications. These applications usually focus on the business’s financial requirements. This means that the data they process is high-value, as it includes critical information related to revenue and business operations. So, because of the fact that these applications store, process and move critical data, they can be big targets for hackers. 

Medical applications 

 Another significant type of critical application are medical applications. These applications manage various confidential data, such as data from doctor’s offices, clinics and other data related to hospitals. The threat of cyber attacks is great in this case as well, because of the importance of the medical confidentiality and medical data. 

Message application 

 Messaging apps are also vital for a company, although many companies don’t give them the required attention. E-mails are used by almost all employees within the enterprise. This gives threat actors the incentive to attack by using messages (such as phishing), to gain easier access to the company. 

Dealing with risks 

 In order to avoid these risks, it is necessary to study critical applications. This way it will be easier to understand the vulnerabilities of critical applications. So, once these vulnerabilities are covered, hackers’ job will be even more difficult since they won’t be able to exploit them as easily. 

Credential attacks 

 A common cyber-attack on businesses is credential attacks. This happens because many companies’ applications are outdated. Therefore, their systems are not strong enough to prevent cyber-attacks. For this reason, a proxy server is necessary. Through this server, authentication is more secure and thus passwords become stronger. The systems in the company will be less at risk from hackers. 

Segregation from exploits and denial of service attacks 

 The process of segregation is done by reducing the traffic so the only protocols that remain are those necessary for the network to operate. This can be done by using firewalls and virtual LANs. Through firewall segregation, the ability to connect various vulnerable services is limited. Thus, by using only the necessary protocols on the network, threat actors are more unlikely to breach the company’s systems. 

Password protection through encryption 

 Another way to increase security in a network is through encryption. In a network there is a lot of confidential data that needs to be kept secure. This can be done by using TLS or VPN gateways. Their goal is to block all traffic from passing through the critical app and encapsulate it into an encrypted tunnel. 


 In conclusion, critical applications are of high importance for a business. The reason is that they contain confidential data, so it is necessary for companies to take appropriate protection measures which Logstail can help with. with the advanced systems and technologies helps you to have full control regarding the security of your systems to prevent a threat or improve a weak point.
