Signals Intelligence (SIGINT) Market Report 2025

This Signals Intelligence (SIGINT) report covers market characteristics, size and growth, segmentation, regional and country breakdowns, competitive landscape, market shares, trends and strategies for this market. It traces the market’s historic and forecast market growth by geography.

The signals intelligence (SIGINT) market size has grown steadily in recent years. It will grow from $14.91 billion in 2024 to $15.51 billion in 2025 at a compound annual growth rate (CAGR) of 4.1%. The growth in the historic period can be attributed to military and defense imperatives, cold war and global conflicts, global terrorism and security concerns, proliferation of cyber threats, civilian and commercial applications.

The signals intelligence (SIGINT) market size is expected to see strong growth in the next few years. It will grow to $19.08 billion in 2029 at a compound annual growth rate (CAGR) of 5.3%. The growth in the forecast period can be attributed to shift towards autonomous and intelligent systems, investments in research & development, evolving nature of threats and adversaries, adoption of cloud-based and big data solutions, regulatory changes and privacy concerns. Major trends in the forecast period include ai and machine learning integration, advanced encryption and decryption technologies, emergence of quantum computing, 5g and IoT impact on sigint, privacy regulations and ethics concerns.

The anticipated growth in the defense budgets of major countries globally is poised to be a driving force behind the signals intelligence market. Safeguarding a nation is a core governmental responsibility, covering its populace, economy, and institutions. National security is a paramount concern for numerous countries worldwide, prompting significant expenditures for establishment and maintenance. In April 2023, data from The Peter G. Peterson Foundation revealed that the United States, in 2022, accounted for approximately 40% of the world's total military expenditures. The U. S. witnessed a $71 billion increase in defense spending from 2021 to 2022, partly due to military aid provided in support of Ukraine during its ongoing conflict. Presently, the United States allocates more funds to defense than the combined spending of the next 10 countries, a notable shift from outspending the next 9 countries in 2021. Hence, the escalating defense budgets of major nations propel the signals intelligence market.

The increasing frequency of terrorist attacks is expected to be a catalyst for the growth of the signal intelligence (SIGINT) market. Terrorist attacks, involving violent actions by individuals, groups, or organizations intending to instill fear, harm, and disruption, necessitate effective monitoring and interception of communication and data associated with such groups. SIGINT plays a pivotal role in providing valuable insights to security and intelligence agencies. As per the Office for the Coordination of Humanitarian Affairs (OCHA), terrorist attacks in 2022 exhibited higher average casualties, with each attack resulting in 1.7 casualties, up from 1.3 casualties per attack in 2021. This marks the first increase in the deadliness of such attacks in five years. Thus, the growing frequency of terrorist attacks is anticipated to drive the signal intelligence (SIGINT) market.

Technological advancement is a significant trend gaining traction in the signals intelligence market. Major players are concentrating on leveraging the latest technologies, such as artificial intelligence, to secure a competitive advantage. Artificial Intelligence (AI) refers to the ability of computer systems to replicate human cognitive functions, enabling them to perform tasks like learning, reasoning, problem-solving, and understanding natural language. For example, in May 2023, Cohere Health, a US-based clinical intelligence company, introduced a new feature that marks the early trend of signal intelligence. This feature is a predictive analytics tool developed by Cohere Health that uses proprietary prior authorization data to forecast medical utilization trends up to three months ahead of claims data. It aims to identify utilization trends, allowing health plans to analyze prior authorization data for early detection of changes in healthcare usage, in contrast to traditional methods.

Major companies operating in the Signals Intelligence (SIGINT) market are actively entering contracts related to various aspects of SIGINT equipment and services to enhance their competitive position. SIGINT equipment and services encompass technology, tools, and support services designed for the collection, analysis, and interception of electronic signals, communications, and data for intelligence and security purposes. As an illustration, in November 2022, Saab AB, a Sweden-based defense and security company, secured a contract for the design, manufacturing, and maintenance of two SIGINT ships for the Polish Ministry of Defense's Armament Agency. This contract was part of Saab's robust order intake in Q1 2023, amounting to SEK 17 billion ($16. 4 billion), marking a notable 110% increase from Q1 2022.

In March 2023, Altamira Technologies Corporation, a US-based technology and engineering services company, acquired Sierra Nevada Corporation (SNC) for an undisclosed amount. The purpose of this acquisition is to enhance Altamira Technologies Corporation's capabilities, expand its customer base, and improve its operations and engineering functions within the intelligence sector. Sierra Nevada Corporation (SNC) is a US-based aerospace and defense company specializing in various key areas within the aerospace and defense industries.

Signals intelligence involves the collection of foreign intelligence through electronic signals and systems used by foreign targets, including radars, communications systems, and weapons systems. This provides a crucial means for a nation to gain insights into the capabilities, actions, and intentions of foreign adversaries. Signals intelligence is utilized by governments worldwide to gather data about international terrorists and foreign individuals, organizations, or powers.

The main types of signals intelligence include electronic signal intelligence, communications intelligence, and foreign instrumentation signal intelligence. Electronic signal intelligence provides situational intelligence, records ELINT (electronic intelligence), and analyzes non-communication radio signals, particularly radar broadcasts. It utilizes a chain of analytical modules and specific passive or active electronic sensors, updating databases with recorded radar signals. Signals intelligence is further categorized by mobility into fixed and man-portable systems, and it finds applications in cyber, ground-based, naval, space, and airborne intelligence.
