Security Monitoring: protecting your business from cyber threats

Hackers or malware, careless or disgruntled employees, outdated or vulnerable devices and operating systems, public and mobile cloud computing, or third-party service providers: in the normal course of business operations, most companies are generally exposed to security threats of varying severity.

Given the omnipresent and unavoidable nature of security risks, system protection strictly requires rapid response times, with continuous and automated security monitoring to ensure quick threat detection and timely countermeasures.

Security Monitoring involves collecting, correlating, and analyzing security information to detect suspicious behavior or unauthorized changes in systems and networks. This activity defines which events should generate alerts and enables the implementation of responses based on detected warnings.

What is Security Monitoring?

Security Monitoring is the monitoring process aimed at identifying cyberattacks and data breaches.

Real-time monitoring of the IT network is a fundamental part of the work required to reduce cyber risk. Organizations that perform Security Monitoring can intercept attacks and respond in minimal time.

In the context of risk management, reducing detection and response times through proactive infrastructure monitoring significantly lowers the likelihood of reputational, financial, or operational damage.

This activity is so important that companies handling extremely sensitive data often rely on Security Operation Centers (SOCs)—24/7 operational centers where cybersecurity experts monitor network security in real time and in person.

Security Operation Centers (SOCs)

The SOC is often considered the most tangible and visible realization of real-time security situational awareness and, given the rapid evolution of digital threats, it remains an important asset for any organization—whether used for internal protection or as a managed service.

Like digital technologies, SOCs have also evolved over time: from centers that merely raised alarms for network events (NOCs), they have progressively been equipped with reactive and proactive capabilities, eventually becoming full-fledged operational centers for proactive monitoring and response, often supported by automated processes.

The main advantage of operating or outsourcing a SOC is the ability to unify security tools, data, and procedures, improving both threat detection and response capabilities.

This typically results in enhanced preventive measures and security policies, faster threat detection, and a quicker, more efficient, and cost-effective response to security threats.

Additionally, a SOC can help increase customer trust and simplify and strengthen an organization’s compliance with national and global privacy and security regulations.

The primary reason to adopt a SOC is the ability to prevent, detect, and respond to attacks through constant data monitoring and event correlation. Although complex and costly to implement internally, a SOC allows defense against attacks of any type, at any time.

Reducing the time needed to identify a threat means being able to intervene before the system is compromised.

How to be prepared

Most cyber breaches are detected after several weeks, some only after months, and often the attack targets involve assets or data whose existence the organization was not fully aware of.

Among the essential solutions for Security Monitoring, Threat Intelligence plays a central role: these tools use data, dedicated expert knowledge, or even artificial intelligence to maintain an up-to-date catalog of the latest threats, giving the network protection system the ability to recognize an attack or malware and take action.

However, it is important not to confuse Threat Intelligence with Security Monitoring. Effective monitoring capable of real-time response requires additional technologies and a clear strategy.

Effective monitoring requires integrated technologies: network security, endpoint protection, IoT environment security, and security for smart-working devices.

Only a combined approach of preventive and proactive actions brings full value to Security Monitoring. Recognizing the latest attacks is important, but so is ensuring a fast and effective incident response.

For this purpose, it is essential to use security products and platforms capable of correlating events and automating analysis, such as firewalls, antivirus software, SIEMs, and increasingly, XDR solutions.

Telsy’s Security Monitoring

Beyond protecting a company from potential threats, security monitoring can also help reduce costs associated with cybersecurity.

For example, by monitoring systems in real time, it is possible to identify and resolve security issues before they cause significant damage, helping to avoid costly remediation efforts.

Telsy offers its customers a dedicated solution for comprehensive monitoring of the ICT infrastructure, enabling them to benefit from the specialist expertise of the company’s SOC and reducing detection and response times in case of anomalies or intrusions.

Telsy’s managed XDR-based service provides integrated capabilities for extended identification, investigation, protection, and response across major attack surfaces (endpoints, servers, email, collaboration). Thanks to automatic event correlation and behavioral analysis, the service reduces detection and investigation times, improving the monitoring and response efficiency of Telsy’s iSOC and ensuring end-to-end protection of the ICT infrastructure.

With our iSOC Security Monitoring & Response and Incident Management services—and with cybersecurity experts dedicated to continuous analysis and reporting—Telsy provides security and protection for the systems of both large and small organizations, allowing the service offering to be tailored to each customer’s specific needs.
