Sigils are cosmetic symbols that can be placed on a Warframe, and are equipped via the Regalia section of the Arsenal. Unlike other Warframe cosmetics like Badges and Emblems, Sigils offer a wide range of customization, allowing players to adjust their size, position and orientation, and players can choose to install them either on the front or the back of the Warframe. Some Sigils also come with their own unique animation effects.
Sigils are primarily acquired through the Syndicates system, with the first Sigil being gifted upon being initiated into a particular group, and further Sigil designs becoming available as one attains favor with said group. Sigils play a very important part in the Syndicates system, as wearing a Syndicate's Sigil when completing missions grants players Standing with them, allowing a player to rise through the ranks to gain rewards. Syndicate Sigil designs have innate Standing multipliers that increase with rank - the higher a Sigil's rank, the larger the multiplier, making wearing said Sigils more effective at acquiring Standing.
Assassins like the Stalker, The Grustrag Three and Zanuka Hunter can also drop their own Sigil designs, and Founders have access to their own exclusive Sigils. Other types of Sigils are also available via different means, including Tactical Alerts. These Sigils however are purely cosmetic, and do not contribute to Syndicate Standing.
These Syndicate Sigils provide different amounts of bonus Standing multipliers depending on rank, determined by which Syndicate rank they were unlocked from:
The starting Sigils provide no bonus Standing.
Rank 1 Sigils = +5%
Rank 2 Sigils = +8%
Rank 3 Sigils = +11%
Rank 4 Sigils = +13%
Rank 5 Sigils = +15%
Additionally, higher ranking Sigils gain more complex animations, with the animation pattern varying between Syndicates.
These Sigils can only be obtained by killing particular Bosses (The Sergeant sigil is the only non-obtainable), and are classified as uncommon drops according to their respective codex entries.

Notes
On the Left: The Zanuka Hunter's Sigil drop (bottom, golden orb) compared to a normal Detron Blueprint Drop (upper, white/pink orb). On the Right: Standard Blueprint Drop appearance (i.e. Oberon Part dropped from an Eximus)
Non-purchased Syndicate Sigils can be previewed in the Syndicates console by clicking on the selected Sigil.
A Warframe cannot equip two Syndicate-affiliated Sigils at the same time, even if both designs are from the same Syndicate. However, a Syndicate Sigil can be equipped alongside any other cosmetic Sigil, such as Founders Sigils.
The Cephalon Simaris Sigil and Conclave sigils are exceptions to this restriction.
Attachments can cover up Sigils, as they are placed on top of the Warframe. Sigils will remain visible above certain Warframe abilities, though, like Iron Skin.
For Sigils with animation effects, the color of the animated portions is determined by the Warframe's energy color.
As of Update 21.0 (2017-06-29), the Velorum Prime Sigil's gold border is now colored by the Sigil tint, with the animated effects set by the energy color of the Warframe.
The Cycuta Prime Sigil's gold border is controlled by the Sigil tint, and the animated effects set by the Warframe's energy color.
Sigils dropped by Stalker and Zanuka will appear as regular violet blueprint "orbs" but will have an additional golden aura resembling an energy or health pickup layered on top (see image on the right).
Sigils dropped by bosses and The Grustrag Three will resemble a mod, but without a sparkling effect. Picking it up will not show a notification and can only be seen by viewing Mission Progress and checking the list of rewards obtained.
