A shielded portal has a floating ring around it when viewed in the scanner. Adding shielding to a portal contributes to its mitigation, which is the percentage of damage from enemy attacks which is blocked, making the portal’s resonators more resistant. A portal’s total mitigation (from shields and links together) is capped at 95; adding more will not increase it beyond that level.
- On 26, December 2018 the Aegis Shield Stickiness was nerfed from 800,000 to 550,000.
The table below shows all combinations of installed shields that do not exceed the 95 mitigation ceiling (not taking links into account):

The Aegis shield (originally branded as the AXA shield) is a variant of the very rare shield. It was introduced on 15 December 2014 through a sponsorship deal with the international investment banking firm AXA, and that variant is adorned with their logo. They are the strongest and stickiest type of shield available. They can be hacked from any portal, but the AXA shield was more likely to be dropped by portals at AXA locations.[source]
On 11 December 2017, Niantic revealed that the AXA shield was to be discontinued, and a new, unbranded shield called the Aegis shield would be released. With the release of version 1.129.2, all AXA shields were converted to Aegis shields, and the AXA shield no longer exists.
