From email authentication to full server infrastructure. ZeroLock IT handles the technical
setup so your team can focus on the business.

Email Deliverability Fix
Your emails are going to spam because the domain is not properly authenticated. Customers are not receiving your messages. That is a revenue problem. ZeroLock IT fixes the DNS configuration so your emails land in the inbox.

SPF, DKIM & DMARC Setup
Missing SPF, DKIM, or DMARC records mean email providers flag your domain as suspicious. ZeroLock IT sets up proper authentication for every platform your business sends from.

Professional Business Email
A Gmail or Yahoo address tells clients your business is not serious. ZeroLock IT sets up a professional email at your own domain, with proper security, so every message you send builds trust instead of undermining it.

Microsoft 365 Security Audit
Most Microsoft 365 tenants are misconfigured out of the box. No MFA on admin accounts. Legacy authentication still active. External sharing wide open. Any one of those is a breach waiting to happen. ZeroLock IT finds every gap and fixes it.
