IT security and protection
The foundation of organizational operationsThe availability of data and information is one of the greatest assets of digital operations. For a company, not only daily operations but also future development depends on its ability to create and maintain a reliable, secure IT environment. The rapidly changing technological landscape and constant online presence bring new challenges: attackers are working with increasingly complex tools, and IT systems are under growing pressure. A single security vulnerability, misconfiguration, or inadequate protection can be enough to cause severe data loss, service outages, or reputational damage—often with legal consequences.
Unicorn’s comprehensive IT security and protection services help our partners prevent these risks and manage them as quickly and effectively as possible. For us, protection is not just a technological issue; we work with a complex approach that takes into account the specific organization’s operations, business goals, and the unique characteristics of its infrastructure. Based on this, we create customized, flexibly scalable protection solutions that not only effectively counter current threats but also prepare for future security challenges.
Our services cover the entire spectrum of IT security: from network perimeter defense, access control, and security backups to the prevention of DDoS attacks. Our experienced experts are actively involved in designing the security architecture from the planning phase and, if required, provide long-term support in operation, monitoring, and maintenance. We believe it is important for our clients not to just try to solve problems with standalone tools, but to build a coordinated, integrated defense system that can respond to threats at every level instantly—and, preferably, prevent them. Protection does not stop at the firewall; it must be present at every endpoint, with every user activity, and at every node where sensitive data or critical operations are handled.
Our services are built on the reliable technologies of leading industry manufacturers (Veeam, Palo Alto, Infoblox, Netscout), which ensure stable operation, scalability, and the highest level of data protection. At the same time, these technologies alone are not a solution—Unicorn’s added value lies in our consulting, implementation, and operational experience, as well as our strategic approach. IT security is not an optional area; it is the foundation upon which every digitally operating organization is built. Unicorn’s goal is to make this foundation secure, transparent, and future-proof.
The layers of security – from the outside in
Our services protect the various layers of IT security, building upon and reinforcing one another. The following sections present the most important areas—following the principle of “defense in depth”. This strategic approach means that we build security solutions from the outside in: starting from the protection of the network perimeter, through attack mitigation and access control, all the way to the protection of user devices and data assets. This is not only a technological but also a business-logical sequence, allowing for the creation of a comprehensive, unified, and effective IT security system that can truly combat today’s threats.
Firewalls – the first line of defense
The security of IT systems begins at the network perimeter—where the corporate network connects with the outside world. Firewalls are security devices that regulate what data traffic can enter or leave the system, thereby forming a primary layer of defense against external attacks. Modern, so-called Next-Generation Firewalls (NGFWs) can filter not only based on IP address, port, and protocol but can also analyze and manage data traffic at the application level. These devices recognize suspicious behaviors and can automatically block attack patterns—even in the case of zero-day threats (a zero-day is a security vulnerability that the software manufacturer is not yet aware of, meaning there is no update or patch for it). Firewalls also provide comprehensive logging and reporting functions, support network segmentation, and can be integrated with other defense systems (e.g., endpoint protection, authentication).
The foundation of the firewall solutions offered by Unicorn is the hardware from Palo Alto Networks, which is among the world’s most well-known and reliable technologies in the field of next-generation network protection. However, it is important to emphasize that the firewall itself—as a physical device—is not sufficient for comprehensive protection. Maximum security and functionality can only be achieved if the device is paired with the appropriate service packages and licenses. One such service is SSE (Secure Service Edge), which enables real-time, context-based inspection of user traffic, even in cloud or hybrid environments.
Encrypted traffic inspection is also of paramount importance: Palo Alto solutions are capable of decrypting SSL/TLS traffic, allowing the system to recognize threats arriving via data transmission encrypted with private keys. This capability addresses one of today’s most critical security challenges, as attackers often exploit the fact that traditional devices cannot analyze encrypted traffic. Our experts help in assembling the appropriate hardware and service package, customizing the security rule set, and, if required, provide support from implementation to continuous operation and support.
DDoS protection system – defending against targeted overload attacks
The goal of DDoS (Distributed Denial of Service) attacks is to overload a company’s IT system and thereby make its services unavailable—for hours or even days. These attacks no longer affect only large corporations or government systems but any organization connected to the internet. Traditional firewalls and IDS/IPS systems are often unable to properly handle the specifics of DDoS attacks because their stateful operation makes them easy to overload themselves.
DDoS defense requires a separate set of devices and a technological approach. Dedicated DDoS protection systems are capable of filtering traffic in a stateless manner (a stateless operation does not track the state of connections, making it much more resilient to overload), recognizing attack patterns, and comparing them with international threat intelligence databases, thus blocking the traffic before it reaches the internal network. They also assist system operations with real-time alerts, reporting, and decision support. For DDoS defense, Unicorn offers solutions from Netscout (Arbor Edge Defense). Both platforms provide an industrial-grade, scalable, and high-availability system for defense, whether against volumetric or application-level attacks.
DDoS testing – Simulated attacks to stress-test your defenses
Most companies only discover the true state of their DDoS protection when it is already too late: when services become unavailable, customers complain, or critical systems go offline. However, technical readiness against denial-of-service attacks involves more than just deploying firewalls, traffic filters, or CDNs—it requires ensuring that the established defenses actually work in practice. This can only be proven through testing.
Unicorn’s DDoS testing service simulates real-world attack scenarios within a controlled and secure environment. We conduct targeted, short-duration, and pre-scheduled stress tests that model various attack vectors—such as volumetric floods, application-layer attacks, and protocol-level exploits. These tests allow us to measure system response times and the capacity of networks and servers, while verifying whether existing DDoS mitigation solutions can effectively respond to threats.
This process is not merely a technical assessment: we provide a detailed report on the results, highlighting detected vulnerabilities, configuration errors, and potential overload vectors. We offer actionable recommendations for fine-tuning your systems or introducing new layers of defense. The result is that the company is protected not just on paper, but possesses real, measurable, and battle-tested security capabilities—ready to face any potential attack with confidence.
Backup – the last line of data security
A company’s data assets are one of the most critical elements of its operation. Lost, damaged, or illicitly modified data can cause serious business harm—from operational shutdowns to legal consequences. The purpose of a backup is to enable the safe and rapid recovery of data in such situations. This is not merely a technical issue but a fundamental requirement for continuous business operations.
Modern backup systems go far beyond periodic data copying. They can back up data from various environments (physical servers, virtualized systems, cloud platforms), manage versions, automatically verify backup success, and even provide protection against ransomware. Unicorn builds its backup solutions on Veeam technologies, which provide an industry-recognized, reliable, and scalable platform. During system design, we consider business needs, backup windows, recovery objectives (RPO and RTO), and the available infrastructure. This way, our clients can always count on their data being safe—even in the event of unexpected incidents.
Security of the core network infrastructure – DNS, DHCP, and IP address management
The reliable operation of a corporate network depends on the smooth functioning of name resolution (DNS), dynamic IP address assignment (DHCP), and IP address management (IPAM). These background systems serve almost all network communication unnoticed, yet they play a key role in maintaining a secure, stable IT environment. If any of these malfunctions—for example, due to an IP conflict, DNS manipulation, or an unauthorized device connection—it can cause serious disruptions in daily operations and even pose a security risk.
The purpose of modern DDI (DNS, DHCP, IP Address Management) solutions is to manage these core functions centrally in a single system while also providing built-in protection mechanisms. This allows for the real-time detection of suspicious DNS queries, the automation of address assignment, and ensures that only authenticated devices can access the network. Unicorn offers DDI solutions that are built on Infoblox technology. The platform can also be integrated into existing IT security systems, providing not only operational stability but also proactive network protection.
Management and system monitoring – transparent it operations in real time
A modern IT system cannot operate effectively without proper monitoring. The goal of system monitoring is to allow the state of the infrastructure to be continuously monitored, analyzed, and optimized—thereby preventing outages, quickly identifying faults, and proactively managing performance problems. In complex systems—be they on-premise, cloud, or hybrid infrastructures—it is particularly important to have real-time information available about the operation of the network and applications.
System monitoring solutions collect data such as network traffic, response times, packet-level statistics, and error rates. Based on these, not only fault detection but also performance optimization, trend monitoring, and capacity planning are possible. This allows system administrators to not only react to a problem but also to prevent it.
The system monitoring solutions offered by Unicorn are built on Netscout nGeniusOne technology, which is a market-leading network and application monitoring platform. The system is capable of providing a comprehensive view of the IT environment’s operation, even in the most complex network topologies. Through transparency and accurate analysis, our clients can confidently manage and develop their IT infrastructure.
