News Item: exida Announces New Whitepaper on the Qualification and Certification of Open-Source Software (OSS)
SELLERSVILLE, PA – March 25, 2026 – exida, the global leader in functional safety and cybersecurity certification, is pleased to announce the release of its latest technical whitepaper: “Qualification and Certification of Open-Source Software.” This landmark document addresses the growing necessity of integrating Open-Source Software (OSS) into safety-critical industrial and…
White Paper: Qualification and Certification of Open Source Software
As Open-Source Software (OSS) becomes essential for high-complexity, safety-critical applications , the industry must bridge the gap between transparent OSS development and traditional, rigid “V-model” safety standards. This whitepaper provides a roadmap for users, maintainers, and integrators to successfully qualify OSS Linux and GNU/Linux projects up to SIL 2 /…
Recorded Webinars: From HLRA to DLRA: Simplifying OT Cyber Risk Assessment with exSILentia Cyber
Considering a Cyber Risk Assessment and don’t know where to start - well we have news for you!
We gathered feedback from both our customers and our own Engineering teams on usability improvements and features, and our software team has delivered!
Allow us to introduce our new revision of exSILentia Cyber with new dedicated HLRA (High Level Risk Assessment) and DLRA (Detailed Level Risk Assessment) worksheets. This new structure follows the IEC 62443-3-2 OT Cyber Risk methodology where an initial Cyber Risk Assessment (HLRA) can first be carried out, followed by a DLRA. Data gathered during the HLRA can be easily brought into the DLRA using smart linking functionality.
We have added many features including:
HLRA:
- Zone Specific Navigation Tree Layout
- Dedicated columns for Devices, threats, and Consequences as well as Non-Hackable Protections
- See your Risk score throughout the process against your risk categories (e.g. Business impact, Safety, environmental - all completely configurable)
- Dedicated column for device-based recommendations
DLRA:
- New DLRA Threat column allowing entry of bespoke device threats
- Link the original HLRA Cyber Consequence into your DLRA Consequence worksheet with ease, using our linking functionality
- Create and build a library of custom countermeasures which can be reused through the DLRA process where applicable
- Build custom countermeasure and categories that align with IEC 62443-3-3 foundational requirements
For both HLRA and DLRA, you can now set a default likelihood during risk setup, which allows each new iteration to be set with an initial likelihood. This can of course be changed after as required.
Join Dwane Shelton as he walks us through a live example of both a High and Detailed level Risk Assessment using our new release of exSILentia Cyber

Blog Entry: When “Worst-Case” Isn’t Good Enough: Why Your LOPA Might Be Underestimating Risk
When designing a Safety Instrumented Function (SIF), practitioners often encounter a complex scenario: multiple initiating events (independent causes) leading to the same hazardous consequence. While common industry practice is to design for the “worst-case” scenario in isolation, this approach contains a hidden danger. A groundbreaking whitepaper from exida reveals why…
Recorded Webinars: What is the Swiss Cheese Model And How Does It Apply to SIS?
The “Swiss Cheese” model is a visual way of demonstrating what happens to a Safety Instrumented System (SIS) and other Independent Protection Layers (IPLs) when not following the IEC61511 lifecycle and/or RAGAGEP (Recognized And Generally Accepted Good Engineering Practices) for the maintenance and mechanical integrity requirements. The “holes” in the Cheese represent a degradation of the SIS and iPLs created by random or systematic faults. These failures result in the “holes” appearing in our model and when all the “holes” line up, this is when the SIS and other protection layers fail to perform their risk reduction task resulting in an incident. This can then lead to severe consequences in terms of explosions, fires, toxic releases, etc.
The webinar ties in the Swiss Cheese model approach to the proper operation and maintenance requirements for the SIS and IPLs, which includes site culture, practices and competency.
What you will learn
- What is the Swiss Cheese model
- What role culture plays in avoiding problems
- What are random and systematic faults and the effects
- What happens when IPLs fail
- What it means to the end user
Who should attend
- SIS designers and Engineering contractors
- Operations and maintenance personnel
- Plant Managers and Supervisors

Blog Entry: Defeating the Swiss Cheese Model: Managing Random and Systematic Failures Across the SIS Lifecycle
How often have you been at conferences where the presenters refer to the “Swiss Cheese Model” ? The intent of the model is to convey what happens to the protection layers in Safety Instrumented Systems (SIS) when they are poorly designed, implemented and maintained. In this case, when any of…
