Anti-Human Trafficking Compliance

Northrop Grumman fully supports the elimination of human trafficking and slavery, including from the supply chain. We do not tolerate trafficking in persons, including the procurement of commercial sex acts, and the use of forced or child labor.

Cybersecurity Resources for Suppliers

As government, prime contractors, and suppliers are increasingly targeted by cyber attacks, companies and their suppliers must work together to protect sensitive information and intellectual property. Awareness of cyber risks and implementation of effective cybersecurity controls and defenses is vital. For timely information about current security issues, vulnerabilities, and exploits, please consult the CISA website.

Northrop Grumman understands the important role our suppliers play in protecting our and our customers’ information and networks from cyber threats. We also understand the value that cybersecurity maturity plays in achieving and maintaining a competitive advantage for our company and our suppliers. Our mutual success is impacted by our ability to both identify and effectively manage cyber risks. Building a cybersecurity posture capable of mitigating risk is essential. Northrop Grumman recognizes that our suppliers must also develop and maintain their own cybersecurity postures. We invite you to view this short video developed through a partnership between the Northrop Grumman Global Supply Chain and Information Security organizations. The video provides recommendations and resources related to some of the biggest cybersecurity challenges including spear phishing schemes, business email compromise and ransomware attacks.

Northrop Grumman has collaborated with other Defense Industrial Base (DIB) companies to establish theCyberAssist Website.  This website will assist suppliers in enhancing their cyber security protections by identifying and posting links to helpful publicly available cybersecurity resources.  The resources were selected both to help companies (i) meet DoD and other U.S. cybersecurity standards applicable to U.S. federal contractors (e.g., FAR Basic Safeguarding clause, DFARS Safeguarding Covered Defense Information (CDI) clause, DoD Cybersecurity Maturity Model Certification (CMMC)); and (ii) otherwise improve their current cybersecurity protections.

Another helpful resource is CI2 Project Spectrum (DoD Small Business Office Sponsored). Part of the Cyber Integrity Initiative (CI2) – and supported by the Department of Defense’s (DoD) Office of Small Business Programs (OSBP), Project Spectrum provides resources, information, training, and risk assessments to help companies and institutions improve cyber readiness and comply with DoD requirements. Suppliers to Northrop Grumman need to comply with our standard terms and conditions.
