Cybersecurity & IT Infrastructure Protection

LS Core specialises in technical cybersecurity for IT infrastructure, security assessments, vulnerability management and remediation. Long-standing Linux/Unix and RHEL experience supports hardening, patching and remediation within an agreed scope — including Windows environments and supported applications where the engagement requires it.

Example delivery flow

The flow below is an example of how security work may be delivered — not a mandatory sequence for every engagement.

  1. 01

    Assess

    Establish systems, objectives, constraints and working conditions before the review starts.

  2. 02

    Prioritize

    Order actions by impact, exposure, dependencies and practical implementation constraints.

  3. 03

    Remediate

    Where agreed, help implement or coordinate the selected remediation work.

  4. 04

    Validate

    Check agreed changes and confirm material findings where it is safe to do so.

Services

Core service areas

We start with the real environment, its constraints and the business objective. Every engagement has an agreed scope, way of working and expected outcomes.

01

Cybersecurity

Technical security reviews, preparation for KSC technical requirements, and remediation planning for infrastructure and systems.

Learn more
02

Security Assessment

Technical assessment of systems, configurations and controls, including technical preparation for KSC without a statutory audit, certification or confirmation of compliance.

03

Vulnerability Management & Remediation

Vulnerability discovery, analysis and prioritisation, with controlled remediation for Windows, Linux and supported applications, subject to tool capabilities and agreed scope.

Context

Cybersecurity Threats in Numbers

Selected, sourced indicators show the scale of incidents and why timely remediation matters. CERT Polska figures and the global Verizon DBIR describe different populations — they must not be merged into one Poland-specific claim.

2026

31%

Share of analysed breaches in which vulnerability exploitation was the initial access vector (DBIR 2026 report).

Verizon DBIR report published in 2026; covers the global breach dataset for the report’s analysis period — not a Poland-only statistic.

Verizon — DBIR 2026 (news release)

Finding vulnerabilities is only the beginning. What matters is how quickly they are remediated.

How we work

How we work

Trust is built on real engineering practice, not fictitious client logos.

Regulated environments

Experience from financial institutions and hybrid environments with high operational constraints.

Scope before promises

We agree scope, inputs and boundaries first. We do not promise outcomes before understanding the environment.

Remediation, not only a list

We connect technical assessment with practical prioritisation and — when agreed — support for implementing fixes.

Development directions

Development directions

AI Security and Private AI are development directions for LS Core, not ready services or products. Work focuses on controlled data use, analytical assistance and human decision-making.

AI Security

Concepts for assisting analysis of events and security information. An area under development, not a ready autonomous product.

Learn more

Private AI

Approaches under evaluation for isolated AI processing with control over access and data flows. Architecture and processing location require separate agreement.
