How Secure64 Approaches DDI Solutions for Security

Updated

Secure64 treats DDI — DNS, DHCP, and IP Address Management — as a security control point rather than just network plumbing. Its approach is to run DNS on hardened, purpose-built software and layer protective services on top of it, so that the same infrastructure that resolves names also filters malicious domains, absorbs attack traffic, and enforces trust in DNS answers. This fits organizations that want DNS-layer threat blocking and DDI consolidation from a single vendor, particularly those with large user bases or government-grade requirements. It is less relevant if you only need a lightweight internal resolver or already run DDI entirely through a cloud provider's native stack.

The DDI foundation

DDI covers three related functions:

  • DNS — resolving domain names to IP addresses and publishing your own zones.
  • DHCP — assigning IP addresses and network configuration to devices.
  • IPAM — tracking which addresses exist, who holds them, and how they are allocated.

Secure64's product line maps onto this stack: DNS Cache, DNS Authority, DNS Signer, DNS Manager, and DNS Proxy cover resolution, authoritative serving, DNSSEC signing, management, and proxying. LineGuard, LineGuard Edge, and Vizion sit above that as cyberthreat protection and content filtering. The company states it has 20 years of DNS experience and supports more than 1.5 billion users globally.

Security services delivered through DNS

The core idea is that DNS sees every outbound connection attempt before it happens, which makes it a natural enforcement point. Secure64 describes Protective DNS (PDNS) as analyzing domain queries in real time to detect and stop malicious activity — blocking access to harmful domains and catching mistyped URLs before a user reaches them.

Secure64 states it has achieved Protective DNS status as recognized by the U.S. Government, and notes that CISA and the NSA maintain a list of pDNS vendors. Its Guard solutions are offered in cloud or on-premises deployments and are described as protecting users, devices, and systems including computers, servers, and IoT infrastructure.

Solution areas

The site groups its work into named solution tracks:

Solution area What it addresses
Building a secure DNS Hardening the resolution and authority layers
DDI solutions Consolidating DNS, DHCP, and IPAM
Security services through the DNS Using DNS as a filtering and threat-blocking layer
Virtualizing the DNS Running DNS functions on virtual infrastructure
Migrating to ENUM Number-to-name mapping for telecom-style services
Deploying DNSSEC Signing and validating DNS answers
Defending against DDoS attacks Keeping DNS available under volumetric attack
Transitioning to IPv6 Moving DDI to dual-stack or IPv6-only

How to evaluate the fit

  1. Confirm the threat model. If your main concern is users reaching malicious or unwanted domains, the Protective DNS and LineGuard layer is the relevant starting point. If your concern is DNS availability under attack, look at the DDoS and authority/cache products.
  2. Decide deployment model. Secure64 offers cloud and on-premises options for its Guard solutions. On-premises suits environments with data-residency or air-gap requirements; cloud suits distributed workforces.
  3. Check the DDI scope you actually need. DNS-only, or DNS plus DHCP and IPAM? The product list separates these, so map your current tooling before assuming a full replacement.
  4. Verify compliance expectations. If you fall under U.S. government protective DNS guidance, the CISA/NSA pDNS vendor list is the reference point Secure64 itself cites.
  5. Ask about pricing directly. The site mentions "predictable pricing" but publishes no rate card, tiers, or free-tier terms. Treat cost as a sales conversation, not an assumption.

Common sticking points

  • Protective DNS is not a firewall. It blocks based on domain reputation and query analysis; it does not inspect payloads or replace endpoint protection.
  • DNSSEC is operational work, not a checkbox. Signing zones introduces key rollover and validation-failure handling that need an owner.
  • Virtualizing DNS changes failure modes. Virtual appliances inherit hypervisor and network dependencies that bare-metal DNS did not have.
  • IPv6 transition affects IPAM first. Address planning and DHCPv6 scope design usually surface problems before DNS does.

For a concrete starting task: inventory your current resolvers, authoritative servers, DHCP scopes, and IPAM records; identify which of the eight solution areas above each one touches; then request a trial through the site's "Try Secure64" entry point with that inventory in hand.
