The global Dark Web Intelligence Market size is projected to surpass the $840 million mark by 2026 growing at an estimated CAGR of more than 20.1% during the forecast period 2021 to 2026. Darknets or networks are connections that are made between or amongst trusted peers and few of them include TOR, Freenet, or the Invisible Internet Project (I2P). Dark Web Intelligence also has prominence in cyber threat intelligence as it monitors, where security insights can be generated that could prevent cyber threats. In terms of business as well, dark web intelligence plays a prominent role as many unindexed websites also has a lot of valuable information that helps the vendors to take the necessary steps. Dark web intelligence also uses dark web forum portals in order to make counter-terrorism and cyber risk analysis activities. Besides, dark web intelligence is also involved in many legal activities like military intelligence, and as a medium to exchange other confidential information.
