The accreditation of the institution from which you received a certification service can be suspended or withdrawn for any reason. In case of suspension, your cerrent certificate can be used in official work and dealings until the end of the validity period. However, when the accreditation of the certification body is cancelled, all certificates that this body provides certification service automatically lose their validity.
Therefore, it is benefical to get services from reliable certification bodies in order not to have problems in official work and dealings and not to lose prestige in front of your customers.
