Packet Block

PacketBlock is a specialist cybersecurity consultancy that embeds with client teams to architect, implement, and maintain enterprise-grade security infrastructure. Its work focuses on protecting digital environments through edge security, DNS architecture, public key infrastructure (PKI), and Zero Trust.

The company designs secure authoritative and recursive DNS infrastructure and supports modern protocols such as DNS over HTTPS and DNS over TLS. Its PKI services automate certificate issuance and lifecycle management using DigiCert, Sectigo, and Let’s Encrypt. PacketBlock also implements identity-based Zero Trust access with tools including Cloudflare Access, Zscaler, and Prisma Access.
