The PART-IS regulation introduced by the European Union Aviation Safety Agency (EASA) marks a decisive turning point in aviation cybersecurity.
This regulation emerges in response to the growing number of cybersecurity standards, regulations, and directives—such as NIS2 (Network and Information Systems Security Directive), the Cyber Resilience Act (CRA), and sector-specific regulations. This expanding regulatory framework reflects the critical need to secure infrastructures and technological products against evolving cyber threats.
At Progressivum, we believe that true business transformation in aviation is only possible when organizations operate with both security and safety at their core. That is why we provide expert guidance in NIS-2 and Part-IS compliance, ensuring businesses not only meet regulatory demands but also secure long-term resilience and growth.This page explores the PART-IS regulation, its implications, scope, key stakeholders, essential requirements, and the steps involved in achieving compliance.
ensuring cybersecurity in critical systems
What is PART-IS?
Why is it essential?
PART-IS was introduced to enhance aviation security by protecting critical information systems in aviation. Its primary objective is to ensure these systems—including avionics communications and air traffic management—are resilient against cyber threats, guaranteeing the continuity and safety of operations in an industry where any failure can have severe consequences.
With the growing integration of digital technologies into aviation, from navigation systems to ground infrastructure, the sector’s vulnerability to cyber-attacks has significantly increased. By requiring aviation industry players to identify and assess system vulnerabilities, PART-IS is a proactive response to today’s challenges.
Protecting digital infrastructure
Which systems are concerned?
PART-IS applies to all digital systems used in civil aviation. These include:
- On-board systems, usch as Flight Management Systems (FMS)
- Air Traffic Management (ATM) infrastructures
- Predictive maintenance systems
The interconnectivity of these systems means that a vulnerability in one component could trigger a chain reaction across the aviation ecosystem, jeopardizing operational safety.
key players in part-is implementation
Who are the stakeholders?
The implementation of PART-IS relies on collaboration between multiple stakeholders, including:
- Airline operators - responsible for the security of on-board systems
- Manufacturers - required to integrate cybersecurity measures into aircraft and equipment design
- Air navigation service providers - tasked with securing air traffic management systems
- National authorities - responsible for overseeing and verifying regulatory compliance
- Ground service providers
PART-IS will be mandatory from October 2025 for organizations approved by EASA under Delegated Regulation (EU) 2022/1645 (production and design organizations). Maintenance organizations under Delegated Regulation (EU) 2023/203 will need to comply by February 2026.
step-by-step approach to regulatory readiness
What are the key stages in achieving compliance?
PART-IS compliance presents a strategic opportunity for companies to strengthen safety, modernize operations, and enhance resilience. With the compliance deadline set for October 2025, now is the right time to start the process.
At Progressivum, we support our clients in three key areas
- Defining the scope - Clearly identifying the impacted systems based on EASA approvals to effectively focus compliance efforts.
- Establishing an Information Security Management System (ISMS) – Structuring policies and processes to proactively manage risks.
- Conducting initial risk assessments – Identifying vulnerabilities and formulating appropriate action plans
These foundational steps establish a long-term information security strategy, designed for continuous improvement in line with PART-IS requirements
building resilience through cybersecurity
Part-IS Compliance: Strengthening Aviation Safety
In today’s digital age, information security and safety are no longer optional—they are essential. Part-IS compliance ensures that organizations adhere to strict security regulations, reducing vulnerabilities and safeguarding critical data.
At Progressivum, we help businesses:
- Assess their current compliance status and identify gaps.
- Implement best practices for data protection and cybersecurity.
- Align with regulatory requirements to mitigate risks and avoid penalties
