About NPSI

Mission

The National Perimeter Security Institute exists to give architects, engineers, security contractors, and end-users — including DOD, CISA-regulated, and commercial facilities — unfiltered facts, testing standards, and engineering specification tools for physical perimeter protection: vehicle crash barriers, anti-ram bollards, high-security fencing, gates, and intrusion detection.

The problem we address

The physical security industry is flooded with misleading manufacturer marketing. Companies self-test barriers, omit payload penetration distances, and obscure the difference between retired Department of State K-ratings and the modern ASTM F2656 standard. The people writing specifications and protecting facilities carry the consequences of those omissions. NPSI publishes the underlying facts so a specifier never has to take a brochure's word for a life-safety decision.

Independence policy

• NPSI sells no products and takes no commission, referral fee, or paid placement of any kind.
• No manufacturer can pay to be listed, ranked, featured, or certified-flagged in any NPSI database.
• Certification flags are assigned only from independent accredited laboratory reports reviewed by NPSI — never from manufacturer literature alone.
• All technical downloads are free and ungated. NPSI does not capture emails or route visitors to sales contacts.

Editorial standards

• Every performance figure published on this site cites its source: the standard, the lab report, or the federal criteria document.
• Claims that cannot be traced to a verifiable source are labeled as claims, not findings.
• Corrections are published openly. If a listed figure is shown to be wrong, the correction is noted on the page that carried it.
• Contributors with a commercial interest in a product category disclose it, and do not author the certification flags in that category.
