Is the website “www.squarespace.com” safe?
As of September 15, 2026 at 12:10, www.squarespace.com has a security score of 88.5/100 (grade B: “Good”).

The website owner should address “Allowed browser content (CSP)” first, then review the remaining items in order of impact.
Does www.squarespace.com show known scam, phishing, or malware signals?
At assessment time, CyStack did not find www.squarespace.com or related infrastructure on any scam, phishing, or malware warning list after checking 5 online reputation sources. This result reflects external observations; it does not guarantee absolute safety or verify the organization’s legal status or reputation.
Potentially exposed domain email addressesChecks infostealer data for email addresses ending in @squarespace.com, the registered domain of the assessed website www.squarespace.com. A record is not counted merely because someone visited or signed in to the website.6 matching email exposure records

These matching email records were observed previously, but they may already have been addressed or may no longer be valid. The device count estimates infected devices associated with these email records; it is not the number of devices owned by the organization.
Frequently asked questions
What affects the security of www.squarespace.com?
A valid SSL certificate still does not prove that www.squarespace.com is safe, legitimate, or free of scam signals. For a more complete assessment, this report also checks phishing and malware, exposed email records, IPs and open ports, subdomains, technologies, and CVEs that may apply to observed versions.
Does www.squarespace.com use HTTPS, and is its SSL certificate valid?
www.squarespace.com used a valid SSL certificate at assessment time, valid until March 4, 2027. This status may change when the certificate expires or the server configuration changes.
Data compiled from CyStack cybersecurity monitoring systems
CyStack compiles scan results from its internal cybersecurity monitoring systems, including CyStack VulnScan and CyStack Threat Intelligence, together with publicly available Internet data. The assessment only observes and analyzes information already available; it does not attempt unauthorized access, test passwords, send exploit code, or change or disrupt the assessed system.
These 3 failed checks or warnings have the greatest impact on the result for www.squarespace.com.
Allowed browser content (CSP)The inspected root HTML response does not include a Content-Security-Policy header.High
Why it matters
Content Security Policy (CSP) limits where scripts, styles, frames, and other browser content may come from. A strong policy reduces the impact if an attacker manages to inject content into a page.
What to do
Define only the sources the application needs, test the policy before activating it, and avoid broad wildcard (*) rules, unsafe-inline, and unsafe-eval where possible.
Scope of this check
This check only evaluates the homepage response and content that the scanner could reach. Other pages and sign-in flows may use different settings.
Protection from deceptive framing (clickjacking)The inspected root HTML response has no effective CSP frame-ancestors or X-Frame-Options restriction.Medium
Why it matters
Another website can place this page inside a hidden or misleading frame and trick a user into clicking an unintended action. Frame restrictions tell browsers which sites, if any, may embed the page.
What to do
Set frame-ancestors in CSP to the required trusted sites, and keep X-Frame-Options for older browsers when appropriate.
Potentially sensitive subdomainsCyStack confirmed at least 1499 active DNS subdomains of squarespace.com. 4 names may expose sensitive services; discovery was partial, so more may exist.Medium
Why it matters
Names containing admin, development, staging, VPN, database, or monitoring terms may point attackers toward valuable systems. A name alone does not prove exposure, but it identifies a surface that should be reviewed.

This is a quick, point-in-time check from outside the organization. It can surface visible risks, but it does not replace penetration testing or an authenticated assessment.
Have @squarespace.com email addresses appeared in exposed data or information-stealer (infostealer) logs?
There are currently 6 exposed email records matching the squarespace.com domain. These records may be old or already resolved. The website owner should verify them before resetting passwords or locking related accounts.
Which public IPs, services, and ports does www.squarespace.com expose?
The assessment observed 4 public IPs and 8 open ports for www.squarespace.com. An open port is not the same as a vulnerability, but the website owner should keep every public service updated and appropriately restrict access.
How many subdomains of squarespace.com have been discovered?
The assessment observed 1,499+ public subdomains of squarespace.com. This list can reveal additional entry points such as APIs, administration systems, or test environments, but it does not mean that every subdomain is risky.
