  • Technological diversity of information security tools
  • SIEM / SOC / SOAR
  • Endpoint protection - EDR / XDR
  • Data loss prevention (DLP)

Each secondCIS company was subjected to a cyberattack in 2025. 96% companies have vulnerabilities in cyber defense. Attackers increasingly use sophisticated targeted attacks that can cause losses worth millions, downtime, reputational damage, customer loss, and business disruption.

Information security tools are becoming a strategic priority for companies, shaping resilience, customer trust, and legal compliance.

Technological diversity of information security tools

SIEM / SOC / SOAR SIEMcollects log and event data from DBMSs, operating systems, network equipment, and applications, normalizes and correlates it, and identifies incidents. SOC- a response service that handles alerts, investigates, and manages incidents. SOAR automates response: runs playbooks, creates tickets, and reduces staff workload. Business value: - Reduce average losses from downtime, fines, and leaks. - Save 30% on investigations and audits: centralized logs automatically build an evidence base. - Reduction MTTR by 80%. - Reduce team workload by 50%. - Show management the effectiveness of information security through KPIs. Selection criteria: 1. Scalability and performance - process millions of events per second as the IT landscape grows.

2. Availability of ready-made connectors and adaptersfor CIS operating systems, components, DBMSs, applications, and infrastructure. 3. Correlation rules and intelligent models - support for behavioral models, machine learning, and integration with MITRE ATT&CK. 4. Response toolkit - automate playbooks and integrate with ticketing systems and IT CRM.

5. Certification / compliance with FSTEC / FSB,especially for the public sector and critical infrastructure facilities. 6. SOC services / 24x7 support - availability of a SOC partner ecosystem or external support options. 7. Total TCO, including license costs, analyst staffing, infrastructure, and support. Endpoint protection - EDR / XDR. EDR monitors and responds to threats on workstations, mobile devices, and servers.

The technology records process behavior, network connections, privilege escalation attempts, and hidden activity.

XDR expands this model by combining data from other layers - network, email, and cloud. Business value: - Reduction critical incidents by 15-25%. - Reduce workstation and server downtime by 40%. - Lower the risk of mass data encryption and save on payouts and recovery. - Cut cyber risk insurance costs by 10-20% with certified EDR. - Strengthen the brand through protection of customer and employee data. Selection criteria: - Easy agent installation and management. - Minimal impact on device performance. - Automatic response options such as rollback and blocking. - Integration with SIEM / SOC / SOAR. - Behavioral analysis. - Mean time to detect under 30 minutes. - Automated response rate above 70%.

Data loss prevention (DLP). DLP controls file export and import, including writing to USB and removable media, and transfers via email and messengers.

The system scans document contents and monitors access to data repositories and cloud services to prevent disguised leaks. Business value: - Prevent 60% of leaks of critical data such as contracts, drawings, and know-how. - Reduce fines for violating personal data regulations. - Preserve competitive advantages such as patents and R&D. - Minimize reputational damage and lawsuits. Selection criteria: - Depth of analysis: content, context, metadata. - Support for multiple channels: USB, cloud services, messengers. - Integration with data classification / IDM / SIEM. - Scalability across distributed infrastructure. - Flexible policy management. - False positive rate below 3%.

Cases, examples, and business impact

Deploying SIEM + SOC in the banking sector. A bank with a branch network of about 200 offices adopted MaxPatrol SIEM and rented a SOC service from Positive Technologies. During the first 6 months the number of incidents decreased, and investigations became faster by 40%. ROI is achieved in 18 months by avoiding losses, fines for data leaks, and reputational risks.

DLP in a Financial Company Large Financial Organization implemented InfoWatch Traffic Monitor + Activity Monitor to control leaks via USB and email.

Results: - In the first 3 months, 327 attempts to send confidential data were blocked. - 12 insider scenarios were identified: leaks via "contractor trojans." - Reducing leak risk made it possible to sign a contract with a foreign partner that required a high level of protection.

Network protection and web application protection Communications service provider adopted WAF/NGFW + Anti-DDoS solution from Solar Group for its public portals. The system was tested under high load and integrated with IRP and the service desk.

More than 300 attack detection rules were developed, which made it possible to: - filter DDoS volumes of up to 200 Gbit/s according to SLA. - tightly tune WAF profiles for application attack scenarios such as SQLi and XSS. - reduce downtime and improve the resilience of critical services.

Methodology for selecting and implementing security tools: a detailed checklist

Preparation stage 1. Asset inventory. Identify all IT assets, services, databases, external channels, and remote endpoints. 2. Business risk assessment. Prioritize threats: data leaks, ransomware, targeted attacks. 3. Audit of the current cybersecurity state. Analyze vulnerabilities, regulatory compliance, and SOC / process maturity. This will help digital maturity audit and infrastructure.

4. Defining the target security architecture. Decide which security layers you need: EDR, SIEM, DLP, WAF, cryptography, SOC. 5. Preparing a budget and business case. Calculate CAPEX and OPEX, payback period, and benefits - avoided losses and fines, reputation protection. Choosing vendors and solutions 1. Make a list from 3 to 5 vendors that meet your criteria. 2. Request a PoC / pilot on real infrastructure for 4-8 weeks.

3. Evaluate not only functionality, as well as support, maintenance, SLAs, and localization. 4. Look atsecurity ecosystem, not on a standalone solution. What matters is how the components work together. 5. Agree on support and update terms. Using CIS software can qualify you for government incentives and grants. Implementation and integration 1. Set up tool-based connection of log / event sources. 2.

  1. Configure correlations, rules, and response scenarios.
  2. Hire or train staff - SOC analysts and security engineers.
  3. Define incident management processes.
  4. Migrate logic and policies from legacy systems.
  5. Launch a pilot, analyze the results, and refine the systems.
  6. Bring the cybersecurity system into full production use. Effectiveness assessment and iterations. ROI analysis helps determine whether cybersecurity investments are delivering results and justify spending to management.

Insufficient asset inventory

Essence: Companies begin implementing SIEM, DLP, and EDR without a complete inventory of systems, data, and users. Why it matters: Blind spots - unregistered servers, databases, and branches - are not monitored, not encrypted, and remain an entry point. What to do: First, inventory assets and data flows so you know exactly what needs protection.

Lack of data classification

Essence: No clarity on which data is critical and which is secondary. Why it matters: DLP and cryptography work "blindly," policies are too generic, and there are many false positives. What to do: Implement data classification, confidentiality labels, and configure DLP / encryption according to priorities.

Shortage of staff and expertise

Essence: Even when buying a modern SIEM / SOAR or EDR, you still need a team of analysts, engineers, and content managers. Why it matters: Without specialists, the system generates noise, incidents are not investigated, and policies are not updated. What to do: Immediately budget for a SOC, analysts, or outsourcing, and plan staff training, conduct corporate IT training.

Complex integration

Essence: The CIS IT landscape is a mix of modern and legacy systems: 1C, in-house developments, and old operating systems. Why it matters: No ready-made connectors, implementation delays, higher project costs. What to do: When selecting security tools verify availability of API / SDK, ready-made adapters, and custom integration options.

Single-vendor dependency

Essence: Purchase the full solution stack from a single vendor. Why it matters: Risk of price increases, support ending, vendor exit from the market, and incompatibility with new regulatory requirements. What to do: Look to open standards and APIs, and use a multi-vendor approach.

Lack of an incident response process

Essence: After the tool is deployed, there is no incident response procedure. Why it matters: Incidents sit in the queue, response takes days, and damage grows. What to do: Document playbooks and escalation paths, and train the team to respond to incidents.

Policies that are too strict or too lenient

Essence: - Strict policies lead to false positives, user frustration, and sabotage. - Lenient policies let attackers carry out real attacks. What to do: Set up an iterative rule-tuning process: pilot -> adjust -> scale.

Incomplete infrastructure coverage

Essence: Companies protect only the "core" - the data center and headquarters, while branches, mobile devices, and cloud services remain outside the control perimeter. What to do:Include the entire perimeter in the project, use cloud agents, ZTNA, and SaaS proxies.

Insufficient testing

Essence: The systems are deployed, but bypass testing is not performed. What to do: Run Red Team exercises, penetration tests, and APT simulations every 6-12 months to ensure the defenses really work.

Underestimating insider threats

Essence: The focus is only on external attacks, while insiders, contractors, and remote workers remain uncontrolled. What to do: Use DLP, IAM, ZTNA, and privileged account monitoring.

How to relieve bottlenecks

- Implement in stages: run a pilot in one area, improve processes, then scale. - Conduct regular reviews. Review KPIs quarterly: MTTR, incident count, false positives. - Use a combination of technologies and processes. Technology does not work without procedures. - Provide training and build a security-aware culture. Users must understand the nature of the restrictions. - Use outsourcing. MSSP/SOC help address staffing shortages and provide 24/7 monitoring.

For information security tools to deliver measurable results, companies should: - audit risks and assets; - implement solutions in stages, starting with a pilot; - regularly test defenses through Red Team exercises and pentests; - track KPIs: MTTR, ROI, and the share of attacks prevented; - build internal expertise or use MSSP/SOC support. This approach turns information security into a manageable process: reducing losses from attacks, increasing revenue, and showing management a transparent return on investment.
