The Covenant has fielded a variety of handheld weapons and devices with electronic warfare uses.

In contrast to humanity's regular use of artificial intelligences in cyberwarfare and intrusion roles, the Covenant considered AIs to be dangerous and vile heresies,{{Ref/Book|Id=Enc22P217|Enc22|Page=217}} citing [[Mendicant Bias|a particular AI]]'s betrayal of the Forerunners.{{Ref/Novel|Id=ch188|CH|Page=188}} However, due to their systems' vulnerabilities to incursion by human AIs, the Covenant unvaulted counter-intrusion constructs in an attempt to combat this issue. Created in ages long past, these constructs are much less sophisticated than their human-made counterparts. On one occasion, the Covenant managed to capture [[Ascendant Justice's AI|a human AI]] and attempted to isolate and convert the machine. This only resulted in a hostile, enslaved mind that managed to escape, replicating itself across many Covenant facilities and vessels.{{Ref/Reuse|Enc22P217}}

The Forerunners developed several advanced forms of electronic warfare technology for use in terrestrial combat. Perhaps most notably, the Forerunners commonly utilized [[baffler]]s and [[dazzler]]s to camouflage objects and areas that they wanted to remain hidden.{{Ref/Site|Id=CryptumGlossary|URL=http://halo.xbox.com/en-us/intel/related/text/cryptum-glossary/62e29c59-a3f9-4b63-af76-def71fda5459|Site=Halo Waypoint|Page=Cryptum Glossary|D=14|M=03|Y=2014|LocalArchive=Halo: Cryptum/Glossary}} The former technology utilizes geometric distortions for camouflage,{{Ref/Reuse|CryptumGlossary}} while the latter technology causes visual and auditory delusions for those within range of the device.{{Ref/Reuse|CryptumGlossary}}<ref>'''Halo: Cryptum''', ''page 41''</ref>

The Forerunner utilized artificial intelligences—called [[ancilla]]—on a scale far surpassing humanity. Ancilla were a standard component of Forerunner [[Forerunner personal armor|personal armor]], interfacing directly with the wearer's mind. The ancilla stored and collated information recorded by the armor and the wearer's own sensory data, allowing both to be accessed later.{{Ref/Novel|Id=SilP41|Sil|Page=41}} In addition to their own stores of knowledge, a personal ancilla could connect to a network—such as that of a starship—and provide information for the wearer at will.{{Ref/Novel|Id=Cry107|Cry|Page=107}} However, the Forerunners' use of ancilla did not stop there. Across their [[ecumene]], trillions of sapient ancilla maintained innumerable aspects of Forerunner society.

The Forerunners also developed a technology for countering ancillas known as an [[AI suppressor]]. These devices were designed to deactivate [[ancilla]]s, capable of debriefing and transferring all the targeted ancilla's data.{{Ref/Novel|Id=Cry194|Cry|Page=194}} The suppressors could also be used to subsume the ancilla within a Forunnder's personal armor or to [[Physical restraints|physically restrain]] an individual, preventing their armor from healing them,{{Ref/Novel|Id=Cry204|Cry|Page=204}} or forcing the wearer into unconsciousness.{{Ref/Novel|Id=Cry208|Cry|Page=208}}
