Espionage-related topics encompass the covert collection, analysis, and dissemination of information that is restricted or sensitive. Espionage is typically conducted by states, political organizations, corporations, or individuals seeking advantages in political, military, economic, or technological domains. It relies on concealment, deception, and the recruitment of trusted insiders, and may involve physical infiltration, social engineering, cyber intrusions, or the coercion of communications channels. Legal frameworks generally criminalize unauthorized intelligence gathering, while state actors often classify information as secret and justify actions under national security.

Techniques and domains include human intelligence (HUMINT), which uses interpersonal contact to recruit sources; signals intelligence (SIGINT), which collects data from communications and electronic emissions; and cyber espionage, which targets networks, supply chains, and data repositories through malware, phishing, and zero-day exploits. Other methods involve document forgery, front organizations, and covert procurement of assets. Espionage activities may be undertaken by national security services, military intelligence, or private-sector entities, sometimes via intermediaries or proxies.

History and context show that espionage has influenced diplomacy and warfare for centuries. In the modern era, it has played a prominent role in the Cold War and in ongoing geopolitical rivalries, as well as in corporate environments where trade secrets and confidential data are at stake. The practice intersects with issues of privacy, civil liberties, and international law, shaping debates over rules, tolerance, and limits on information gathering.

Countermeasures and policy responses include counterintelligence programs, cybersecurity measures, personnel vetting, physical security, and incident response planning. International norms and treaties aim to regulate cross-border intelligence activities while balancing national security with other interests.
