The first zero-trust DNS filtering and secure web gateway service

Open and uncontrolled DNS resolution is a security vulnerability. Attackers relentlessly use cheap, disposable, and compromised Internet resources to stand up domains and websites to attack your employees and organization at will. We map the Internet in real-time and separate the trusted from the hostile. Our patent-pending technology proactively defends your end-users wherever they are in ways that any other DNS firewall, DNS filter, and secure web gateway simply can't. In less than 5 minutes, we'll stop threats and access to hostile Internet resources that can compromise your end-users and result in a business compromise or data breach.

How Securd defends against cyber attacks.

It's likely your traditional defenses won't detect the phishing email and your end-user will miss or ignore a warning banner. If an end user clicks on the threat, or opens a malicious attachment, we're there to stop the threat. Securd provides multiple layers of defense to prevent your endpoint from downloading malware, accessing a command and control server or being further compromised. Securd offers a proactive defense to block attackers' use of cheap, free, disposable, and compromised Internet resources to attack your organization.

Proactive DNS & web defense to protect end users.

Attackers will continue to come up with ways to get end users to fall for the phishing, click on malicious links, and open malicious attachments.

Your end-users are busy, distracted and focused on their job. Because phishing resembles legitimate email, phishing emails will evade most anti-spam, anti-virus and anti-malware software. Our security approach assumes all traditional security controls have failed, warning banners have been ignored and threat intelligence does not exist to defend against the threat.


Cloud-delivered DNS security for any organization.

Securd can be used by any business, regardless of size or location. It takes most administrators less than 5 minutes to get started.

Deployment requires only a simple change to your network DNS settings. Getting remote employees working from home protected is just as easy. We offer agent and agent-less options to get your remote and off-network devices protected. No matter what plan you select, you will also gain visibility into real-time and historical logs to investigate and remediate incidents.
