Über Institut Polytechnique de Bordeaux
Bordeaux Polytechnic Institute (Institut Polytechnique de Bordeaux, IPB) is a leading French higher education institution encompassing multiple engineering schools and training programmes. As a major academic organization, IPB manages a complex email perimeter that includes official communications with students, parents, institutional partners and government agencies, as well as internal communications across administrative and pedagogical departments. The ipb.fr domain represents the institution's digital identity and serves as a critical channel for transmitting sensitive information related to admissions, diplomas and digital services. Securing email flows through DMARC, SPF and DKIM authentication is essential to prevent domain spoofing, phishing attacks and CEO fraud targeting IPB stakeholders. Higher education institutions face particular risks of impersonation, as attackers seek to masquerade as the institution to steal student data or conduct financial fraud. Given its role as a critical entity, IPB must comply with evolving cybersecurity requirements, including the NIS2 Directive which strengthens security obligations for essential service operators. DMARC authentication of the ipb.fr domain therefore represents a fundamental step in ensuring trust in the institution's official communications and protecting its institutional reputation.
