For many security clearance holders (federal employees and government contractors), most security concerns traditionally center on foreign contacts, finances, or handling classified information. Increasingly, however, another issue is emerging as a significant national security concern: the commercial collection and sale of personal digital data and its impact on individual clearance holders.
Today, data brokers, mobile applications, fitness trackers, and location-based services are generating massive amounts of seemingly private information about Americans, including cleared personnel, and much of that information may already be available for purchase or can be gathered by foreign powers.
Government officials and national security experts have repeatedly warned that commercially available data can be exploited by foreign intelligence services and other adversaries. Keeping an eye on your data as a clearance holder is very important.
The Rise of Data Brokers
Many people are unaware that an entire industry exists to collect, bundle and sell personal data. Data brokers gather information from:
- Mobile applications
- Advertising networks
- Social media activity
- Loyalty programs and purchases
- Public records and online behavior
These companies often compile highly detailed profiles without consumers realizing it. According to the Privacy Rights Clearinghouse, data brokers collect and sell personal information from sources with which consumers may have no direct relationship.
For clearance holders, the issue is not merely privacy, it is protecting security and your security clearance.
Location Tracking and Sensitive Facilities
Location tracking applications and mobile advertising data have become a major national security concern because they can reveal movement patterns around sensitive government and military locations.
Recent reporting and research have shown that commercially available location data has exposed the movements of military and intelligence personnel both domestically and overseas. Congressional lawmakers recently warned that foreign adversaries may still be able to purchase location data tied to sensitive U.S. government facilities, including personnel movements near federal sites.
For cleared personnel, seemingly harmless apps that track movement, weather, traffic, or advertising preferences may generate highly revealing location histories. For example, we have seen cleared personnel on dating apps who have been tracked and contacted for dates by potential foreign interests (as they later found out) solely because they lived within a certain radius of a sensitive facilities’ location.
Fitness Trackers and Wearable Devices
Fitness trackers and wearable technology present another underappreciated risk. If you go on the Apple or Google App stores, there are countless fitness tracking programs available, many free of charge. This issue has been ongoing since before 2018, when the DoD/DoW banned fitness/GPS trackers during deployments.
At that time, public attention focused on fitness tracking data that revealed activity patterns near sensitive military installations. The concern remains relevant today because wearable devices have improved accuracy and continue collecting:
- GPS location data
- Daily movement routines
- Sleep patterns
- Health and biometric information
When combined with other commercially available data, these details can help identify where cleared personnel work, travel, or spend time.
Commercial Data and Intelligence Targeting
Perhaps the most significant concern is how commercial data can be used for intelligence targeting. Research involving military personnel data has shown that foreign actors could potentially use commercially available information to:
- Track movements and routines
- Identify government affiliations
- Build detailed personal (health, dating history, debts, social media history) profiles of clearance holders
- Conduct phishing or influence operations
- Target individuals for exploitation or recruitment
A Duke University study examining military personnel data concluded that commercially available data creates serious vulnerabilities that could be exploited by foreign adversaries.
This represents a major shift in the intelligence landscape. Information that once required sophisticated espionage efforts may now be obtainable through commercial marketplaces.
What Cleared Personnel Should Consider
Cleared professionals should increasingly think about digital privacy as part of overall security awareness.
Practical steps may include:
- Knowing the background of the apps you download
- Reviewing app permissions regularly
- Limiting unnecessary location tracking
- Exercising caution with foreign-owned apps
- Understanding how wearable devices store and share data
- Using privacy and device security settings more aggressively
The issue is no longer simply personal privacy, it is national security exposure through commercial data ecosystems.
Final Thoughts
The digital privacy risks facing cleared personnel continue to grow as commercial data collection becomes more sophisticated and widespread. Data brokers, location tracking applications, fitness devices, and foreign-owned platforms all contribute to an environment where highly sensitive personal information may already be available for sale. It is only a matter of time before the government institutes new measures to restrict clearance holder use of certain apps that are found to be a national security problem.
Clearance holders should at least understand the risks of technology in connection with their security clearance and security obligations. The combination of commercial data and modern analytics has created new opportunities for intelligence targeting and foreign exploitation. The bottom line is that those with security clearances should be careful with their phones, tablets and the apps they use.
