55 tools
This category collects tools that protect data and communications: encrypted messaging apps, file and disk encryption, secure deletion utilities, password managers, and anti-tracking software. For OSINT practitioners, these serve two purposes at once. They secure your own research, sources, and identity, and they help you understand the privacy technologies that subjects of an investigation may be using to shield themselves.
When evaluating a tool, favor open-source, audited software with strong, modern cryptography and an active maintenance record. Understand what each tool actually protects, data at rest, data in transit, or metadata, since no single tool covers everything. Use encryption to safeguard sources and comply with data-protection duties, not to evade lawful accountability.

is a free and open-source password manager that uses the most secure encryption algorithms to safegard your passwords.
a security-focused desktop operating system that aims to provide security through isolation.
Investigators use encryption to protect sensitive sources, case notes, and their own identity from interception or theft. Encrypted messaging and file storage safeguard communications with contacts and secure evidence at rest. Understanding these tools also helps researchers recognize the privacy technologies that subjects of an investigation may rely on.
Encryption at rest protects stored data, files, disks, or backups, so it stays unreadable if a device is lost or seized. Encryption in transit protects data moving across a network, like messages or web traffic, from interception. Comprehensive security needs both, since a tool covering only one leaves gaps.
Open-source tools allow independent experts to audit the code and verify there are no hidden weaknesses, which builds trust over time. That transparency is valuable, but security also depends on active maintenance, sound implementation, and real audits. A well-maintained, audited tool is generally preferable to closed software with unverifiable claims.
