SENTIZONE Defense

Cyber security for your organisation: Layer 7 protection, defence in depth and documented NIS2 compliance.

Why organisations choose us

  1. Addresses known to be malicious, and regions with no operational relevance, are stopped at the door.

  2. Attack patterns are identified in real time and the source is blocked automatically.

  3. The internal network is segmented, and the footprint visible from outside is reduced.

  4. We do not deliver policies alone: we implement the controls and supply the evidence.

The legal framework we work within

  • NIS2
  • Directive (EU) 2022/2555
  • GEO 155/2024
  • Law 124/2025
  • DNSC Orders 1–3/2025
  • GDPR
  • ISO/IEC 27001

Who we are

We design, implement and operate the digital security of your organisation.

We deliver perimeter and network security on our own firewall platform, installed at a single point of control through which all traffic between the internet and the internal network passes. Because it is our own solution rather than an off-the-shelf product installed in hundreds of thousands of environments, the attack surface is smaller and less predictable.

The defence

Controls ordered from the checks with the lowest processing cost, at the network edge, through to the adaptive mechanisms inside it.

Preventive blocking

Threat intelligence feeds reject public addresses known to be malicious, grouped by attack category, and geo-blocking policies remove traffic from regions you have no operational relationship with. Both act before the session is established.

Stateful L3/L4 filtering

Traffic is permitted or blocked by IP, port, protocol and connection state. Only correctly initiated sessions get through.

Layer 7 inspection

Exposed protocols are analysed to identify traffic that is permitted at port level but abusive for the service concerned.

Behavioural detection

Logs are read in real time, patterns such as brute-force, scanning or credential stuffing are identified, and the source is blocked automatically, with a ban duration that grows exponentially.

Network segmentation

Isolated zones that limit lateral movement and the blast radius in the event of a compromise.

Secure DNS

DoT, DoH and DNSSEC encrypt queries and validate responses, reducing exposure of connection metadata.

How we work together

Six stages, each with a deliverable that serves both as proof of compliance and as the starting point for the next stage.

Assessment

We establish whether and how the law applies to you. Deliverable: the applicability file.

Registration

We complete the standard form and handle correspondence with DNSC.

Risk analysis

We determine the risk level and maintain an up-to-date risk register.

Measures plan

Maturity self-assessment, gap analysis and remediation priorities.

Implementation

Firewall and detection, segmentation and VLANs, MFA, hardening, encryption and logging.

Managed services

Continuous monitoring and response, outsourced security officer, reporting.

We assess the current situation together, and the evidence that is missing. The first step is a conversation, not a commitment.
