The Hidden Threats in Corporate Mail
Enterprise organizations face invisible dangers from mail and deliveries. Despite advanced security protocols, harmful substances continue to infiltrate facilities, threatening employees, executives, business continuity, and brand reputation.
WHY ENTERPRISES FACE HIGHER MAIL THREAT RISKS
Despite strong perimeter and digital defenses, enterprises face significant vulnerabilities in their mail flows putting employee safety and business operations at risk.

INSIDER THREATS & POLICY BACKLASH
Layoffs, policy changes, or internal disputes can fuel insider retaliation, making disgruntled employees a significant source of corporate mail threats.
BRAND REPUTATION, POLITICS & VISIBILITY
Brands that appear aligned with one side of a controversial societal or geopolitical issue can become a direct target for those with opposing views.
EXECUTIVE-LEVEL TARGETING
High-profile leaders are often viewed as synonymous with the company itself — increasing their exposure to targeted, mail-based attacks.
HYBRID & REMOTE WORK
Mail for employees who aren't in the office every day often sits uninspected, creating windows where threats such as electronic cyber-attack devices can remain undetected. Additionally, mail routed to employees' homes puts family members at risk.
ALL-IN ONE DETECTION OF CBRNE THREATS
MailSecur detects all types of mail threat categories listed by the US Department of Homeland Security, including:

BIOLOGICAL
Materials that may carry diseases with the potential to spread.

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

THREATENING CONTENT
Suspicious mail with menacing language on envelope or contents.

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

RADIOLOGICAL
High-energy radiation materials that have adverse health effects.

Nuclear
Explosive devices utilizing nuclear reactions.

SUSPICIOUS POWDERS
Powder threats including anthrax, ricin, fentanyl, and hoaxes like sugar or baking soda.

DANGEROUS ITEMS
Weapons, sharps, or other items that are intentionally harmful and temporarily disrupt activities.

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

Corporate / Executive Protection FAQs
Why is mail a threat to corporations?
Mail is a low-cost, anonymous, and high-impact threat vector. Explosive devices, toxic powders such as ricin, anthrax, or fentanyl, and small electronic devices can be sent through mail. Even hoaxes can disrupt operations, damage brand reputation, and reduce employee morale. Lax mail security processes make mail an increasingly exploited attack vector.
Is MailSecur safe for office environments?
Yes. MailSecur uses safe, non-ionizing T-ray technology. It requires no radiation safety permits or licenses and can be deployed in any office environment.
How is MailSecur different from X-ray?
X-ray provides static 2D images, generates ionizing radiation, requires safety controls, and is not sensitive enough for many modern mail threats. MailSecur delivers live 4D imaging using safe T-rays and is significantly smaller and more sensitive for detecting powders, liquids, and electronics.
How does MailSecur protect executives?
MailSecur detects hidden threats in sealed mail before it reaches executives. Screening unopened mail protects screeners from dangerous contents while preserving the privacy and confidentiality of executive communications. MailSecur can be deployed in corporate offices, executive residences, and mobile operations such as vehicles, boats, and aircraft.
Where is MailSecur used?
MailSecur is used in Fortune 500 and Global 2000 headquarters, regional offices, data centers, manufacturing and R&D facilities, executive residences, and mobile screening operations.
How does MailSecur support protective intelligence?
MailSecur provides insight into mail threat activity, emerging trends, and risk factors that are often blind spots for protective intelligence teams, enabling a more complete risk landscape.
Are there guidelines or best practices governing mail screening?
RaySecur collaborates with organizations to develop tailored SOPs, best practices, and security guidelines aligned with each facility's operational requirements.
How fast is screening?
Screening takes seconds. MailSecur provides a real-time live video view of concealed contents inside mail items.
Is MailSecur recognized by government authorities?
Yes. MailSecur is designated a Qualified Anti-Terrorism Technology by the U.S. Department of Homeland Security under the SAFETY Act and is also used by leading U.S. and international government agencies.
What are the trade-offs between onsite MailSecur screening and outsourced mail screening services?
Onsite screening provides speed, control, and visibility by detecting threats in real time without opening packages. Unlike outsourced services, it avoids delays, protects sensitive information, integrates with existing security protocols, and offers a scalable, cost-effective solution.
