The "European border surveillance system" (EUROSUR) is a Frontex information-exchange framework founded in 2013, tightening border control. It links all Schengen area countries, plus Bulgaria, Romania and Croatia. Each country contributes with a National Coordination Centre (NCC), which collects local and national data about border events like irregular migration or crime. It makes use of drones, offshore sensors, reconnaissance aircraft and satellite remote sensing. It runs on a budget of €244 million between 2014 and 2020. Critics have expressed human rights concerns over EUROSUR's intrusive modus operandi using drones and satellites.

eu-LISA, the European Agency for the operational management of large-scale IT systems, mange three central data bases. These collect data, including biometric, about persons wanted by police, visa applicants, asylum seekers and irregular migrants. They also hold information on stolen objects. The agency is well-funded: its budget almost doubled in a very short time, having shot up from approximately €49 million in 2014 to over €80 million in 2016. As of late, the European Commission proposes that EU-LISA adds databases connected to an entry-exit system which store information on non-EU nationals crossing Schengen borders. To add to it, the Schengen area states are planning to adopt a European Travel Information and Authorisation System (ETIAS), asking non-Europeans to apply for entry to the EU, similarly to U.S.' ESTA system. #database"

European Maritime Safety Agency (EMSA) sits on a budget of over €54 million. It was designed to control maritime safety and security in EU waters. EMSA has gradually become part of European Union’s border security system, sharing objectives with Frontex. The agency is exploring the idea of operating a fleet of drones and take part in a broader multi-million surveillance system that gathers data. EMSA was also mandated to prevent and respond to pollution caused by ships or by oil and gas installations.

European Satellite Center (SatCen) has been involved in border surveillance projects, furnishing Frontex with satellite imagery and information on the presence of fishing vessels in North Africa. A Statewatch report mentions that FRONTEX also requested SatCen for services related to the current migrant crisis. Its budget is €12,26 million.

The European Defence Agency contributes to the development of military projects and backs objectives that stimulate investments in defence across Europe. "Industry takes a front seat in the EDA decision-making process, with easy access to all relevant players," an EUobserver report said. €90m may be poured into defence research by 2019, with EDA’s chief executive Jorge Domecq citing citizens’ security.

European Fisheries Control Agency’s primary role is to ensure that EU’s common fisheries policy rules are not breached. However, the European Court of Auditors have found essential shortcomings in the EU fisheries regime that jeopardised compliance. The EFCA collaborate with Frontex by delivering vessel monitoring data through a satellite-based surveillance system. This can identify the location and speed of vessel and track their course.

The European Union Institute for Security Studies (EUISS) was founded in 2002. It is responsible for foreign, security and defence policy-related analysis. It also acts "as an interface between European experts and decision makers".

The European Space Agency (ESA) is an independent intergovernmental agency. It supports EU’s environment and security monitoring systems. As part of the Copernicus Security Services, it supplies EUROSUR with border surveillance intelligence by mapping and monitoring of border areas. It also detects security threats for the EU External Action. And it weighs in for EU’s maritime surveillance, law enforcement and marine pollution operations. These services build on a series of projects developed with EU funds, such as FP6 and FP7 among many.
