Perry Ryan has agreed to join the Hawks.
The former Pompey defender has been snapped up by Shaun Gale after spending pre-season on trial at the club.
Ryan moves to Westleigh Park after being released by the Blues at the end of the last campaign.
He was a member of the squad who toured north America last summer, winning the Edmonton Cup.
Ryan spent the second half of last season on loan at Bognor.
The Hawks have also signed former Farnborough and Fleet Town keeper Lyall Beazely.
