Notable former members of the band include vocalists Paul Baloff and Steve "Zetro" Souza, drummers John Tempesta and Paul Bostaph, and founding guitarist Kirk Hammett who later joined fellow Bay Area thrash metal band Metallica.

Holt, who has been in the band since 1981, is the only member to appear on every Exodus album.

The band is currently composed of Angelripper, guitarists Frank "Blackfire" Gosdzik and Yorck Segatz, and drummer Toni Merkel. Sodom has been referred to as one of the "Big Four" of Teutonic thrash metal, along with Kreator, Destruction and Tankard. Sodom heavily influenced the German black metal scene, and is regarded as a pioneer of death metal. Referred to as the most Venom-blackened of German "Three Kings", Sodom further merged thrash and death metal into a "wicked and decadent sound."
