The airport security market is witnessing high growth. Continued innovation in this space towards automation, digitalization, and minimal human involvement will shape its future outlook.

Market Drivers

The airport security market is driven by several key factors, such as increasing passenger traffic, new airport construction projects, and technological advancements.

  • Increasing passenger traffic – The global aviation industry has seen tremendous growth in passenger traffic in recent years. According to IATA, global passenger traffic increased by 6.5% in 2017 compared to 2016. The growth is being fueled by both developing economies as well as mature aviation markets. The rise in passenger traffic is leading to increased security requirements at airports. Airports are upgrading their security systems and protocols to handle larger crowds and ensure passenger safety.

  • New airport construction projects – With air passenger growth outpacing available airport capacity, there is a boom in new airport construction projects globally. According to the CAPA Centre for Aviation, there are over 200 new airports or terminal projects underway. Large new projects like Beijing Daxing International Airport and Istanbul New Airport have comprehensive security infrastructure plans. Additionally, upgrades at existing airports also drive demand for new security technologies and systems.

  • Technological advancements – The airport security technology market is evolving rapidly with new innovations focused on greater accuracy, speed, and ease of use. Advanced X-ray scanners, explosive trace detectors, biometric systems, and AI-based threat monitoring systems are some areas seeing focused R&D activity. Airport operators are keen to adopt smarter security technologies to enhance both security and passenger experience.

Screening Systems

Airport security screening systems are used to detect prohibited items and contraband being brought onto aircraft or restricted areas. Key types of screening systems include:

  • Passenger screening – Technologies like walk-through metal detectors, full body scanners, explosive trace detection systems, and advanced imaging technology are used to screen passengers and their carry-on luggage before entering the airport terminal or boarding the aircraft. This ensures no prohibited items like weapons or explosives are brought onboard. Advanced systems use 3D imaging, millimeter waves, and automated threat recognition software for more effective passenger screening.

  • Baggage screening – Checked luggage goes through X-ray machines and CT scanners to identify dangerous objects and materials inside bags. Explosive detection systems (EDS) use computed tomography to automatically recognize explosives. Some airports also use inline baggage screening systems during baggage handling to streamline security.

  • Cargo screening – Cargo and freight shipped by air must also undergo screening. Techniques like X-ray scanning, explosive detection systems, and canine teams trained to sniff out explosives are used to inspect cargo for threats. 100% screening of all cargo on passenger flights is required by many countries.

Investments in next-generation screening technologies along with stringent security regulations are key drivers propelling the growth of the airport security screening systems market worldwide.

Access Control

Access control systems are critical for airport security to monitor and restrict access to restricted areas. This includes technologies like perimeter intrusion detection, video surveillance, and barriers.

Perimeter intrusion detection systems use radars, sensors, and cameras to detect any unauthorized access into restricted zones. These systems can differentiate between animals, debris, or actual security breaches. Some airports also use active infrared beams that can detect when the beam is broken.

Video surveillance technology allows airport security to visually monitor airport terminals, hangars, runways, and other sensitive areas. High-definition cameras provide detailed video footage that can be analyzed using video analytics software. Surveillance footage is stored and recorded for incident investigation purposes.

Physical barriers and bollards are used to create chokepoints and deny vehicle access near terminals. Retractable road blockers allow authorized vehicles to pass during permitted times. Crash-rated active vehicle barriers are used at airport perimeters and near buildings. Interlocking metal barriers make it difficult to force through checkpoints.

Access control combines various systems to restrict and control access to sensitive airport areas. Advanced integration and analytics of access control systems are crucial for airport security.

The airport security market is rapidly adopting new technologies to enhance efficiency and improve the passenger experience. Some of the key technologies shaping this industry include:


Facial recognition, iris scanning, and fingerprint matching are becoming commonplace at airport security checkpoints. Biometrics provides a touchless and automated way to verify passenger identities and streamline processes. Major players like Clear and CLEAR Me are using biometrics for expedited screening. Integrating biometrics into e-gates also enables automated border checks.

Artificial Intelligence

AI algorithms are being deployed for automated threat detection in X-ray scans of baggage. Machine learning models can flag suspicious items or anomalies for further inspection. AI is also powering chatbots and virtual assistants to provide customer service and travel information to passengers. Looking ahead, AI could be used for behavior analysis to identify potential security threats.

Advanced Screening Systems

New sophisticated screening tools provide detailed 3D imagery of baggage contents, reducing the need for manual bag searches. Millimeter wave scanners offer high-resolution body scans to detect concealed objects without physical contact. Backscatter X-ray scanners bounce X-rays off a person’s body to uncover hidden items. These technologies enhance threat detection while improving the screening experience.

Sensor Fusion

Combining data from a network of sensors provides deeper insights than a single sensor alone. CCTV surveillance paired with acoustic sensors, infrared cameras, and radar can better analyze events and improve threat response. Integrating multiple detection technologies creates a more accurate and reliable airport security ecosystem.


With airports becoming highly connected environments, securing networks, data centers, and equipment against cyber risks is critical. Airport security systems must embed cybersecurity best practices like encryption, access controls, and vulnerability testing. Robust cybersecurity safeguards airports against sabotage, data breaches, and operational disruptions.

Embracing advanced technologies along with vigilance and training helps maximize airport security while maintaining privacy and facilitating air travel.

With air travel rising globally each year, several regulations have been implemented to enhance airport security. These regulations aim to detect threats while balancing efficiency and passenger experience.

The key regulations agency in the United States is the Transportation Security Administration (TSA), which oversees all transportation security including airports. Following the 9/11 attacks, the TSA created and implemented new screening requirements for all checked baggage. Regulations have progressively been tightened by the TSA over the years to improve security effectiveness. Key regulations include:

  • Mandatory screening of all passengers and baggage
  • Banning of certain items in carry-on bags like knives, liquids, gels, aerosols, etc.
  • Requirement for shoes, jackets, and belts to be removed during screening
  • Mandatory full-body scanning or enhanced pat-downs for all passengers
  • Limitations on liquids, gels, and aerosols to 3 oz or fewer containers carried on planes
  • All electronics larger than phones must be removed from bags for X-ray screening

In Europe, airport security is regulated by the European Civil Aviation Conference (ECAC), which establishes baseline security protocols. However, each country can implement additional measures as they see fit. Some examples of key regulations include:

  • Similar carry-on liquid restrictions to the US
  • Mandatory passenger and baggage screening
  • Common rules against bombs or incendiary devices
  • Recommended use of security scanners
  • Requirements for cockpit door locking and screening of pilots

As threats continue evolving, security regulations will need to be constantly updated to counter the latest risks and keep air travel safe. Regulations balance passengers’ rights with the priority of security effectiveness.
