Single point of contact for security

Cybersecurity vulnerabilities and incidents affecting SENECA products, firmware, software, services and systems.

Your contribution helps us make our products and the ecosystems in which they operate more secure.

01 Regulatory framework

New European rules bring cybersecurity from IT to the field

Machines, gateways and controllers are now part of the attack surface. Three regulatory levels, three different targets: the organisation, the product and the individual OT component.

Organisation

NIS2

Directive (EU) 2022/2555 • Italian Legislative Decree 138/2024

  • Essential and important entities: risk management, incident response and business continuity.
  • Notification of significant incidents within 24 h / 72 h (to ACN / CSIRT Italia in Italy).
  • Supply chain: machinery and automation suppliers must demonstrate that their products are secure by design.
  • Penalties of up to €10 million or 2% of turnover.

Product

Cyber Resilience Act

Regulation (EU) 2024/2847

  • Essential requirements for all products with digital elements placed on the EU market.
  • Secure by design and by default, security updates throughout the support period, SBOM.
  • From 11/09/2026: reporting of actively exploited vulnerabilities and severe incidents via the ENISA Single Reporting Platform.
  • Penalties of up to €15 million or 2.5% of turnover.

OT component

IEC 62443-4-2

Technical requirements for IACS components

  • 7 Foundational Requirements: authentication, use control, integrity, confidentiality, data flow, events and availability.
  • Security Levels from SL1 to SL4 for each Component Requirement (CR).
  • The technical method for demonstrating alignment with the CRA and NIS2 at device level.

RED Delegated Act – EN 18031

Since 1 August 2025, connected radio products (Wi-Fi, LTE, etc.) must meet the cybersecurity requirements of Delegated Regulation (EU) 2022/30, with the harmonised standards EN 18031-1/-2/-3. Once the CRA fully applies, these requirements will be incorporated into the new framework.

Machinery Regulation (EU) 2023/1230

From 20 January 2027, the new Machinery Regulation introduces requirements for protection against corruption and unauthorised access affecting safety: automation components integrated into machinery become part of the manufacturer’s assessment.

02 SENECA’s approach

Security by Design, built into the device

Security is not a cloud service added afterwards: it is integrated into the device’s hardware, firmware and network. IEC 62443 is the design reference; results are verified by third parties.

Defence in depth

Process – PSIRT, vulnerability management, CVD

Remote access – encrypted VPN, 2FA, local consent

Network – separate LAN/WAN, OT/IT segmentation

Device

Product Security / CRA workflow

Vulnerabilities and incidents affecting SENECA products

Reports concerning products with digital elements follow the Product Security & Vulnerability Management process: impact assessment, firmware/software updates, corrective measures and notifications required by the CRA.

How we handle a report

1. Receipt

Acknowledgement of receipt and unique PSIRT-AAAA-NNN identifier.

3. Analysis

Reproduction, CVSS assessment, affected products and versions.

4. Remediation

Temporary mitigations, development and validation of the fix.

5. Advisory and closure

User communication, Security Advisory and case closure.

Information to include in your report

  • Product, model and product code
  • Hardware version and firmware/software version
  • Description of the vulnerability or incident
  • Steps to reproduce or necessary conditions
  • Potential impact
  • Logs, evidence and any Proof of Concept
  • Any observed exploitation
  • Reporter’s contact details

Do not send passwords, credentials or unnecessary personal data.

Email security@seneca.it

Coordinated Vulnerability Disclosure

SENECA applies a coordinated disclosure approach. After receiving a report, it:

  • assesses the severity of the vulnerability;
  • identifies affected products and versions;
  • defines any temporary mitigations;
  • develops and validates the fix;
  • informs affected users;
  • publishes a Security Advisory where appropriate.

We ask reporters not to publicly disclose exploitable details before a mitigation or fix is available. On request, the researcher’s contribution may be acknowledged in the advisory.

Cyber Resilience Act – Art. 14

Reporting to European authorities

From 11 September 2026, SENECA reports actively exploited vulnerabilities and severe incidents affecting the security of its products via the ENISA Single Reporting Platform to the coordinating CSIRT (CSIRT Italia / ACN in Italy). The reporting channel for authorities does not replace security@seneca.it, which remains the point of contact for customers, users, partners and researchers.

24 h Early warning to the competent authority
72 h Notification including product, impact and initial measures
14 days / 1 month Final report (vulnerability / severe incident)

SENECA Security Advisories

Advisories include CVEs, CVSS scores, affected products and versions, the fixed version and recommended measures. New advisories are identified as SENECA-SA-AAAA-NNN.

Date Advisory CVE CVSS v3.1 Affected products Action / fixed version
15/09/2026 Security notice for STRATON Editor 6.71 and earlier
Ref. STRATON Security Advisory ID #321328 (Copadata) – PDF
CVE-2026-84854 7.0 High Windows workstations with SENECA STRATON IDE/PACKAGE 1.9.1.0 and a green Wibu dongle (WibuKey driver ≤ 6.71). SENECA controllers and RTUs are not exposed. Update the WibuKey driver to version 6.72 or later

Report management

Each report is recorded confidentially, classified, assigned to the relevant technical teams and assessed against regulatory obligations, in a timely, proportionate and confidential manner. SENECA may contact the reporter for further information. Information is shared only with teams that need it and, where required by law, with the competent authorities.

Security activities and testing

Activities that compromise system availability, modify or delete data, access unnecessary personal or confidential data, compromise third-party systems, DoS/DDoS attacks, social engineering or any unlawful action are not authorised. If you accidentally access confidential data, stop the activity immediately and inform SENECA.

Organisation and responsibilities: the model involves the Information Security Team, Product Security / R&D, IT Manager, Quality & Compliance, the NIS2 point of contact, legal teams and Management. This model enables SENECA to distinguish and correctly manage incidents affecting company infrastructure and those affecting product security.

06 FAQ

Frequently asked questions

Does the Cyber Resilience Act apply to SENECA products?

Yes. The CRA covers all products with digital elements, meaning hardware and software with firmware or a direct or indirect data connection to a device or network. This includes gateways, RTUs, dataloggers, I/O modules with communication interfaces and SENECA software.

What changes from 11 September 2026 and 11 December 2027?

From 11/09/2026, manufacturers must report actively exploited vulnerabilities and severe incidents via the ENISA platform (24 h / 72 h / final report). From 11/12/2027, all essential requirements apply: products placed on the market must comply with the CRA and bear CE marking also covering cybersecurity.

Do products already installed need to be replaced?

No. The CRA’s design requirements apply to products placed on the market from 11/12/2027. However, the reporting obligations under Art. 14 also apply to products already on the market: this is why SENECA handles reports on all products, including those installed before that date.

How do I report a vulnerability or incident?

Email security@seneca.it with the product, code, hardware/firmware versions, description, steps to reproduce, impact and any evidence. You will receive an acknowledgement with a PSIRT identifier. Do not send passwords or credentials.

How will I be informed about vulnerabilities and updates?

SENECA informs affected users and publishes Security Advisories on this page and in the Newsroom, including mitigation measures and fixed versions. You can subscribe to the SENECA newsletter to receive technical updates.

How long does SENECA provide security updates?

The CRA requires manufacturers to define a support period for each product, normally no shorter than 5 years unless a shorter use is expected, during which security updates must be provided. SENECA will specify the support period in the documentation for CRA-compliant products.

What is IEC 62443-4-2 and what does SL4 mean?

It is the standard defining technical security requirements for components of industrial automation and control systems (IACS). Each requirement can be met at a Security Level from SL1 (protection against accidental violations) to SL4 (protection against sophisticated attacks with extensive resources). For the PASS / SSD series, the independent assessment documents the Security Level achieved for each applicable requirement, up to SL4.

How do SENECA products help my facility comply with NIS2?

NIS2 requires risk management throughout the supply chain as well. Devices with strong authentication, encryption, segmentation, audit logs and secure updates, together with independent testing and compliance documentation, provide the evidence required in questionnaires and audits for essential and important entities.

Do SENECA radio products comply with the RED Delegated Act?

Connected radio products placed on the market from 1 August 2025 are subject to the cybersecurity requirements of Delegated Regulation (EU) 2022/30 (EN 18031). Models such as Z-LTE-CEI and MY2-CEI comply with the RED DA; for other models, the product’s EU Declaration of Conformity is authoritative.

Does SENECA provide an SBOM for its products?

The CRA requires manufacturers to draw up a software bill of materials (SBOM) as part of the technical documentation. SENECA is integrating the SBOM into its release process; information on third-party components can be provided on request as part of audits and security questionnaires.

How can I verify the authenticity of SENECA firmware?

Download firmware and software only from the official website www.seneca.it or through SENECA support channels. On PASS / SSD series devices, firmware is digitally signed and secure boot prevents unauthentic images from starting.

What configuration best practices do you recommend?

Change credentials at first login, enable 2FA where available, disable unused services and ports, separate the OT network from the IT network, use only encrypted VPNs for remote access (e.g. LET’S / VPNBOX2), send logs to a SIEM, back up the configuration and install security updates regularly.

What does the new Machinery Regulation mean for those integrating SENECA products?

From 20/01/2027, machinery manufacturers must consider protection against corruption and unauthorised access that could compromise safety. Components with documented IEC 62443-4-2 requirements, intervention logs and traceable updates simplify this assessment.

May I perform security tests on SENECA products?

Yes, on devices you own and in test environments, in accordance with the rules set out on this page: no impact on production or third-party systems, no DoS against SENECA services and no social engineering. Report results to security@seneca.it in line with coordinated disclosure principles.
