Top DFARS Cybersecurity Challenges And How To Overcome Them

Author : Ariento Inc | Published On : 28 Apr 2026

In today’s defense contracting environment, cybersecurity compliance is no longer optional—it is a strict requirement. Businesses working with the U.S. Department of Defense (DoD) must comply with complex regulations such as DFARS cybersecurity standards. However, many organizations struggle to fully understand and implement these requirements. This article explores the most common challenges related to DFARS 252.204-7019, DFARS 252.204-7020, and DFARS CMMC, along with practical ways to overcome them, with insights from Ariento.

Understanding DFARS Cybersecurity Requirements

The DFARS cybersecurity framework is designed to protect Controlled Unclassified Information (CUI) within the defense supply chain. Key clauses like DFARS 252.204-7019 and DFARS 252.204-7020 require contractors to assess and report their cybersecurity posture using the NIST SP 800-171 framework. Additionally, DFARS CMMC introduces a certification model to validate compliance.

Despite clear guidelines, organizations often face significant roadblocks in implementation.

Challenge 1: Lack of Clarity in Compliance Requirements

Many companies find it difficult to interpret the technical language in DFARS 252.204-7019 and DFARS 252.204-7020. Understanding how these clauses apply to their specific operations can be confusing.

Solution:

Partnering with experts like Ariento can simplify the process. A professional assessment helps translate regulatory requirements into actionable steps. Clear documentation and gap analysis ensure your organization knows exactly what needs to be done.

Challenge 2: Conducting Accurate Self-Assessments

One of the core requirements of DFARS 252.204-7019 is completing a self-assessment based on NIST SP 800-171. Many organizations either overestimate or underestimate their compliance score.

Solution:

Use structured assessment tools and involve cybersecurity professionals. Ariento offers guided assessments that provide accurate scoring and help identify gaps. This ensures your submitted score reflects your true compliance level.

Challenge 3: Preparing for DoD Audits

Under DFARS 252.204-7020, contractors must be ready for DoD audits. Many businesses are unprepared for the level of scrutiny involved.

Solution:

Regular internal audits and mock assessments can significantly improve readiness. Ariento helps organizations prepare audit-ready documentation, ensuring that policies, procedures, and controls are properly implemented and documented.

Challenge 4: Implementing DFARS CMMC Requirements

The introduction of DFARS CMMC adds another layer of complexity. Companies must achieve certification levels based on their handling of sensitive information.

Solution:

Start early and adopt a phased approach. Ariento assists in building a roadmap aligned with DFARS CMMC, helping organizations implement controls step-by-step rather than all at once. This reduces risk and ensures smoother certification.

Challenge 5: Resource and Budget Constraints

Small and mid-sized businesses often lack the resources to implement full-scale DFARS cybersecurity measures.

Solution:

Prioritize critical controls first. Focus on high-risk areas such as access control, incident response, and data protection. Ariento provides cost-effective consulting solutions that align with your budget while ensuring compliance.

Challenge 6: Continuous Monitoring and Maintenance

Compliance is not a one-time task. DFARS Cybersecurity requires ongoing monitoring and updates to maintain security posture.

Solution:

Implement continuous monitoring tools and regular reviews. Ariento helps establish long-term cybersecurity strategies that include monitoring, reporting, and improvement plans.

Final Thoughts

Meeting DFARS 252.204-7019, DFARS 252.204-7020, and DFARS CMMC requirements can be challenging, but it is achievable with the right approach. By addressing common obstacles and leveraging expert support from Ariento, organizations can strengthen their DFARS cybersecurity posture, reduce risks, and stay compliant.

Investing in proper planning, expert guidance, and continuous improvement will not only help you meet compliance standards but also build trust with defense partners and stakeholders.
