Deep dives, practical guides, and incident analyses from engineers who build Safeguard. No fluff, no vendor FUD — just what you need to ship secure software.
What crypto agility really means, why SHA-1's decade-long death proved it, and how to design algorithm swaps into software before NIST's PQC deadlines force the issue.
A practical buyers guide to quantum-safe VPN options, comparing Cisco, Palo Alto Networks, Mullvad, ExpressVPN, Zscaler, and Post-Quantum on real strengths and limitations.
FIPS 203's ML-KEM Kyber is landing in TLS, SSH, and VPNs everywhere — here's how the lattice math works and the timing bugs, like KyberSlash, already found in real implementations.
A cryptographic bill of materials (CBOM) inventories every algorithm, key, and certificate in your systems—here's why PQC migration is impossible without one.
A Merkle tree is a hash-based data structure that lets transparency logs prove data integrity efficiently, using Merkle proofs and certificate transparency.
A concrete guide to certificate transparency logs: how SCTs verify issuance, how CT monitoring works, and how rogue certificates get detected fast.
What is a hash collision, and why does it break integrity checks and signatures? A precise definition, the SHA-1 collision attack, and how Safeguard closes the gap.
HMAC is a cryptographic construct that combines a hash function with a secret key to verify both the integrity and authenticity of a message.
A precise, technical answer to what is elliptic curve cryptography — plus how ECC vs RSA, ECDSA signatures, and ECDH key exchange secure modern systems.
