About Us


Mission Darkness, by MOS Equipment, is a global leader in radio frequency (RF) shielding solutions. Our products play a pivotal role in supporting law enforcement and military forensic investigators. We specialize in the secure collection, analysis, and preservation of digital evidence, a critical aspect in maintaining the integrity and chain of custody essential in criminal investigations. Our product range includes mobile device analysis enclosures, shielded lockers, and specially designed faraday bags, all tailored for the secure handling of digital devices. These solutions are crucial in protecting sensitive information from risks such as remote hacking, tracking, and unauthorized access, thereby enhancing the operational effectiveness of law enforcement agencies worldwide.

At Mission Darkness, our commitment extends beyond product development. We are dedicated to high-quality manufacturing, continuous innovation and patented designs, and exceptional customer care. Our aim is not just to meet industry standards, but instead to set them. We believe our products are more than tools; they are a promise of justice and public safety in the digital age. Join us in the mission.


We believe that every human has the right to safety, security, and privacy. As we introduce new devices into our lives that see us, listen to our conversations, and track our whereabouts, these fundamental rights become nearly impossible to achieve at the sacrifice of convenience.

Our mission is to give the control back to you. Stay private at home, stop cell phone hackers while in public, prevent your car from being stolen, protect your electronics from an EMP, block a criminal from remote wiping critical digital evidence, safeguard sensitive data on your laptop... The choice is once again yours.

Meet the team members who passionately innovate, improve, and support our quality-driven products.


Faraday Bags

Our complete line of faraday bags provides instant data security for cell phones, tablets, laptops, and other electronic devices by preventing wireless signals from reaching or leaving the device while enclosed inside. They are a necessity when handling digital evidence, since they protect devices from remote wiping and alteration to maintain chain of custody. Our wide variety of bag sizes, styles, and outer materials ensures that there is a shielding solution for any type of mobile device or scenario. Additional features include transparent windows, built-in shielded USB filters, and charging kits.

Analysis Enclosures

Mission Darkness analysis enclosures and other forensics products offer the ultimate radio frequency shielding and hands-on accessibility for electronic device forensics investigations. Specialized features allow users to operate touch screens in order to conduct cell phone and tablet triage, analysis, and extraction while keeping devices shielded inside the enclosure.

Shielded Lockers & Charging Cabinets

We offer a variety of lockers and cabinets designed specifically for forensic investigators to keep devices individually locked, shielded, and charged during storage. These products are used primarily in the front office, while devices wait for an investigator to analyze them. The charging feature prevents lockout mode and reduces the amount of time needed to break a passcode, enabling the maximum amount of data extraction and unlocking with additional forensic tools like GrayKey, Cellebrite, Magnet, XRY, BlackBag, Oxygen, etc.

Faraday Tents

We offer a diverse collection of faraday tents and shielded vehicle covers designed for a range of specialized applications, including digital forensics and electromagnetic pulse (EMP) protection. These tents are engineered with the highest quality materials and "seamless construction" to ensure exceptional shielding effectiveness, providing an enclosed space that blocks all wireless signals, thereby securing sensitive information and protecting electronic equipment from external electromagnetic interference.

Custom Orders

We're dedicated to creating products that keep your devices offline. Our development team can design and manufacture custom faraday enclosures based on your specific shielding needs and dimensions. We can add shielded filters to most bags and also offer custom labeling for bulk orders; contact us for more details.

Quality Assurance

Mission Darkness products block all wireless signals including cell, Bluetooth, RFID, Wi-Fi, and GPS, to ensure that your devices are offline and protected against hacking, tracking, eavesdropping, RFID skimming, EMF radiation, EMPs, and remote accessing or data wiping. The Mission Darkness line will continue to expand as we meet the needs of our customers worldwide. Our products are backed by decades of combined industry experience, IEEE 299-2006 and MIL-STD-188-125 lab certifications, plus our ironclad shielding guarantee.

Made in the USA

The majority of our products are made and/or assembled in the USA. Some of our components and bags are made abroad, primarily due to a lack of availability in the USA. We are a proud supporter of American manufacturing and will continue to sacrifice profit to bolster local jobs.

The majority of our products can be made to Berry Amendment standards. They require a lead time to produce and are priced higher than the standard version listed on our website (which is not Berry Compliant). Contact us to discuss options if you have Berry Compliant requirements.
