Government Facilities are the Number One Target of Mail Threats
Close the gap in your security posture. RaySecur helps government facilities stop hidden dangers at the envelope with 4D T-ray mail screening and expert program design.







Mailroom Vulnerability in Government Security
For the price of a first-class stamp, a letter can be sent anonymously and conceal any number of threats, including powders, liquids, explosives, or electronics that disrupt operations, harm staff, damage reputation, or trigger costly legal and media fallout. Perimeter controls are critical — but mail and parcels bypass traditional checkpoints every day.
Why Government Facilities Face Higher Mail Threat Risks
Federal, state and local government facilities remain the number one target for mail threats – both hoaxes and legitimate attacks. Even with strong perimeter and digital defenses, government facilities face unique vulnerabilities in their mail flows:

Government offices receive mail from many external sources—including public, legal, and legislative correspondence—making each item harder to vet.
Federal, state, and local agencies often span dozens of buildings, each with its own mailroom and limited screening.
Government facilities represent national authority, making them primary targets for ideologically motivated threats.
Courthouses, municipal offices, and public service centers welcome hundreds of visitors and deliveries daily.
Complex procurement cycles and budget limitations can delay upgrades to modern screening technology.
From white-powder hoaxes to advanced CBRNE threats, government mail threats grow more sophisticated each year.
All-In One Detection of CBRNE Threats
MailSecur detects all types of mail threat categories listed by the US Department of Homeland Security applicable to government facilities, including:

Materials that may carry diseases with the potential to spread.

Improvised explosive devices (IED), pipe bombs, and related threats.

Suspicious mail with menacing language on envelope or contents.

Prohibited items such as illicit drugs, cell phones, and electronics.

High-energy radiation materials that have adverse health effects.

Explosive devices utilizing nuclear reactions.

Powder threats including anthrax, ricin, fentanyl, and hoaxes.

Weapons, sharps, or other items that are intentionally harmful.

Toxic or poisonous powders, liquids, and solids, including laced-papers.
