Security software: Selection, comparison criteria and trends

Every day, IT security systems thwart millions of attempted attacks around the world. Nevertheless, cybercriminals regularly manage to penetrate corporate networks. This often has severe consequences. According to the Bitkom study "Wirtschaftsschutz 2025" (Economic Protection 2025), cyberattacks will cause damages of 289.2 billion euros in Germany alone in 2025. This marks a new record high. 87% of companies were affected by such attacks this year.

In such times, a robust IT security structure is especially crucial. But there are many questions: Which IT security software is the best? How do endpoint security tools differ from other cybersecurity solutions? And how do individual tools form an effective IT security concept?

In this article, you will learn about the types of security software, important criteria for comparison, and trends in cybersecurity solutions.

What is security software?

Security software protects your IT infrastructure from cyberattacks, data loss, and system downtime. It keeps your systems running and your data secure. Every IT security software pursues three central protection goals:

• Confidentiality: Only authorized persons are allowed to access sensitive information.

• Integrity: Data remains complete and unchanged. No manipulation is possible.

• Availability: Systems and data can be reliably used at any time, even in the event of an attack.

Security software also works proactively. It is deeply anchored in the operating system, is updated by continuous threat databases, and often detects suspicious activities before actual damage occurs.

What types of IT security software exist?

The selection of IT security software is vast. Which cybersecurity solutions you need depends on your IT architecture and risk analysis.

Antivirus and anti-malware software

These tools detect and block viruses, trojans, worms, and spyware. In this way, they provide effective protection against damage. Classic antivirus programs identify known threats using signatures. New cybersecurity solutions combine this method with behavioral analysis and thus also detect unknown threats (zero-day attacks).

Endpoint security tools at a glance

Endpoint security tools protect all endpoint devices in your network, whether laptop, desktop PC, smartphone, or IoT device. They combine multiple layers of protection:

• Endpoint Detection and Response (EDR): Continuously monitors endpoints and detects suspicious activities in real time.

• Application Control: Determines which programs are allowed to run.

• Patch Management: Installs security updates automatically.

Example: A company with 200 employees uses endpoint security tools to centrally monitor all laptops. When an employee opens a phishing email, the EDR system detects the suspicious activity, automatically isolates the device, and thus prevents it from spreading to other systems.

Firewalls and network security

Firewalls control the data traffic between different networks. Next-generation firewalls not only analyze sender addresses but also applications and content. They prevent attackers from moving freely within the network after a breach. These cybersecurity solutions are crucial for network segmentation.

Security Information and Event Management (SIEM)

SIEM systems are the centerpiece of your IT security. They collect log data from all security sources and analyze it in real time. As a central IT security software, they enable rapid responses to security incidents.

Encryption and backup software

Encryption protects data from unauthorized access, both during transmission and at rest. Backup solutions enable the recovery of your systems after a ransomware attack. Immutable backups, which attackers cannot manipulate, are crucial.

Selection criteria for comparing security software

A structured security software comparison helps make the right decision. Pay attention to these criteria:

Range of functions and integration

When comparing security software, check whether the solution covers only basic protection or offers multiple layers of protection. API interfaces for the seamless integration of your IT security software into existing systems like SIEM platforms are important.

Detection rate and performance

Look for high detection rates combined with a low false alarm rate. Independent testing institutes such as AV-TEST provide valuable indicators for your security software comparison. Conduct a proof of concept in your environment to test performance impacts.

Central management and scalability

A central management console is indispensable. You should be able to roll out security policies, monitor endpoints, and generate reports from a single dashboard.

Compliance support

Regulatory requirements such as GDPR, NIS-2, or ISO 27001 demand verifiable security measures. Your IT security software must offer audit-proof logging and customizable reports.

Current trends in cybersecurity solutions

Three trends are particularly shaping the development of cybersecurity solutions:

AI-supported defense

Attackers use AI for automated phishing campaigns. Defenders deploy AI-supported cybersecurity solutions to detect anomalous behavior through data analysis that signature-based systems miss.

Professionalized ransomware

Ransomware-as-a-Service (RaaS) enables even less technically proficient criminals to carry out attacks. Modern endpoint security tools with XDR (Extended Detection and Response) functions detect attacks in their early stages and interrupt them automatically.

Zero trust architectures

The zero trust principle is: "Never trust, always verify." This approach is based on micro-segmentation (dividing networks into small areas), least privilege access (minimum rights), and continuous verification of every access.

Creating an IT security concept for software

Individual software solutions only reach their full potential as part of an overarching IT security concept. You therefore need a blueprint that coordinates all components and places them within a strategic framework.

An effective IT security concept for software comprises four steps:

1. Inventory and risk analysis: Record all IT components in a Configuration Management Database (CMDB). Identify vulnerabilities and evaluate risks.

2. Define protection goals: Determine which information is particularly worthy of protection. Define concrete requirements based on legal regulations.

3. Implement measures: Select appropriate security software and supplement it with organizational regulations.

4. Continuous improvement: The PDCA (Plan-Do-Check-Act) cycle ensures continuous adaptation to new threats.
   
   

Documentation of security software and endpoint security tools

Seamless documentation of your security software is a critical component for rapid responses to security incidents. The NIS-2 directive, for instance, makes IT documentation a central security factor.

Structured documentation of your IT security software should include the following points:

• Inventory: Record all security software components and endpoint security tools centrally in a CMDB.

• Overview of protective measures: Document which measures protect which asset and how effective your cybersecurity solutions are.

• Proof of compliance: Your IT security software documentation must provide evidence for ISO 27001 or BSI IT-Grundschutz.

• ISMS integration: Your documentation should be part of a comprehensive IT security management system.

i-doit Suite and INDITOR® ISO: The software solutions for your IT security concept

With its i-doit GRC Suite+ and INDITOR® ISO, i-doit specifically supports companies in systematically documenting security software:

• Central documentation: Record all deployed cybersecurity solutions and endpoint security tools.

• Transparency: Gain a practical overview of your protective measures and their effectiveness.

Without the right security software, companies are vulnerable

Choosing the appropriate security software is a crucial factor on the path to digital resilience. The right combination of endpoint security tools, cybersecurity solutions, and supplementary measures wards off cyberattacks and pays into compliance.

Lay the foundation for the right decision with a thorough security software comparison. By integrating it into a comprehensive IT security concept with current tools, you ensure one thing: technical and organizational measures mesh perfectly. Additionally, detailed documentation ensures transparency and flawless proof of compliance.
