In the world of cybersecurity, the concept of “good enough” is no longer relevant. Digital transformation, hybrid working models and cloud migration processes have blurred the boundaries of corporate networks. There is no longer a single “castle gate” to protect; instead, there is a massive and dispersed attack surface consisting of thousands of endpoints, cloud workloads, and IoT devices.
While traditional Security Operations Centers (SOCs) are overwhelmed by thousands of daily alert fatigues from disjointed security tools, attackers take advantage of this confusion and silently move through networks. This is where Extended Detection and Response (XDR) emerges as a paradigm shift , not a product update.
As Infosec, we discuss in detail why the Proactive XDR approach, which we offer with our global experience and leading technology partners such as Check Point, Palo Alto, and CrowdStrike, is a vital investment for your business.
Why Traditional SOC Architecture Falls Short
Security in the traditional structure; It is managed in “silos” such as EDR (Endpoint), NTA (Network Traffic), SIEM (Log Management), and Email security. The main problems created by this structure are:
- Data Silos and Blind Spots: EDR only sees the endpoint, Network Firewall only sees traffic. When the attacker enters with an e-mail, escalates authority at the endpoint, and makes lateral movement over the network; These three different tools cannot see the big picture because they do not talk to each other.
- Alert Fatigue: Analysts are forced to manually sift through thousands of “low priority” alerts from different screens. According to industry data , 44% of security analysts are forced to ignore some of the alarms they need to investigate due to workload.
- Slow Response Times (MTTR): The time between threat detection and response (Mean Time to Respond) allows enough time for the attacker to encrypt or steal data.
Infosec XDR Approach: Integrated and Intelligent Defense
XDR (Extended Detection and Response); It collects data from all security layers such as endpoint, network, cloud, email and identity management in its raw form, combines it in a single repository and analyzes it with artificial intelligence (AI).
The infosec XDR architecture is not just an “aggregator” but a “senser”.
1. Integration Without Limits in Visibility
Infosec XDR service melts data into a single pot by protecting your existing security investments (e.g. your existing Firewall or EDR solution) with its technology-agnostic “Open XDR” vision. Whether on-premise or multi-cloud , we leave no blind spots.
2. Behavioral Analysis with Artificial Intelligence
Signature-based protection has been dead for a long time. Our XDR platform uses machine learning algorithms to map your organization’s “normal” behavior.
- Example: A user pulling a large amount of data from a server they normally don’t access in the middle of the night may not be subject to traditional rules, but for XDR it is an Anomaly and generates an immediate alarm.
3. Automated Intervention and SOAR Power
XDR doesn’t just report the threat it detects; stops. Our system, which works integrated with SOAR (Security Orchestration) capabilities:
- It isolates the infected device from the network.
- Blocks the malicious IP address in the Firewall.
- Temporarily suspends the user account (Active Directory).
- It does all this in seconds, without the need for human intervention.
Scenario Analysis: How to Stop a Ransomware Attack?
Let’s explore the difference between traditional methods and the Infosec XDR approach with a concrete scenario:
Scenario: An employee clicks on a malicious Excel file in a phishing email. The file runs a PowerShell command in the background.
CISO Spotlight: XDR's Strategic Contributions to the Business (ROI)
For a security manager, the added value that technology provides to the business is as important as technology.
1. Reducing Operational Costs
Sifting through thousands of unnecessary alarms reduces the burden on Level 1 (L1) analysts by 70-80%. This allows your team to focus on strategic threat hunting rather than routine tasks.
2. Closing the Qualified Personnel Gap
It is difficult to find trained experts in the cyber security sector. Infosec XDR service acts as a virtual army of hundreds of experts for your organization with its automation and managed service (MDR/MSSP) layer.
3. Business Continuity and Reputation Protection
The average cost of a cyberattack is measured in millions of dollars. Stopping the attack before it is “data leaked” or “system encrypted” protects not only the IT budget but also the company’s market reputation and customer trust.
4. Full Compliance with Regulations
Standards such as KVKK, GDPR, PCI-DSS, and ISO 27001 require “prompt notification” and “detailed forensic analysis” in case of violations. The in-depth reporting capability offered by XDR strengthens your hand in audit processes.
Frequently Asked Questions (FAQ)
Why do we need XDR when we have an existing SIEM solution?
SIEM is great for broad log management and compliance, but it can sometimes be cumbersome in threat detection and response. Rather than replacing SIEM, XDR is the muscle power that strengthens its detection ability and takes “action”. We at Infosec are creating a hybrid force by integrating SIEM and XDR.
Which security products does the Infosec XDR service integrate with?
Thanks to our “open architecture” principle, we provide full integration with solutions from global manufacturers such as Check Point, Palo Alto, Fortinet, Cisco, CrowdStrike, Microsoft Defender and many more. You don’t need to throw away your existing investments.
How long does the installation process take and will it disrupt our operation?
Thanks to its cloud-based and agent-supported structure, the Infosec XDR service can be deployed quickly without interrupting your existing workflows. Full visibility is usually achieved within days.
Is the Threat Hunting service included in this package?
Yes. The Infosec XDR service is not just about automated tools. Working 24/7, our expert SOC analysts proactively search for and hunt for silent and sophisticated threats on your system using the MITRE ATT&CK framework.
Don't Leave Your Safety to Chance
While cyber attackers use artificial intelligence and automation, you have no chance of winning with manual defense methods. Modernize your defenses, illuminate blind spots, and secure the future of your business with Infosec Proactive XDR Service .
