Does www.siteimprove.com show known scam, phishing, or malware signals?
At assessment time, CyStack did not find www.siteimprove.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 @siteimprove.com, the registered domain of the assessed website www.siteimprove.com. A record is not counted merely because someone visited or signed in to the website.8 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.siteimprove.com?
A valid SSL certificate still does not prove that www.siteimprove.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.siteimprove.com use HTTPS, and is its SSL certificate valid?
www.siteimprove.com used a valid SSL certificate at assessment time, valid until March 3, 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.siteimprove.com.
Allowed browser content (CSP)The CSP on the inspected root HTML response contains a broad, unsafe, or missing script-source control recognized by this bounded check.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.
Evidence and check scope
Configured:
Yes
Number of policies:
1
Weak settings found:
Broad Script Source, Unsafe Eval, Unsafe Inline Without Nonce Or Hash
DMARC blocking policyThe effective DMARC policy is quarantine and applies to 100% of messages.High
Why it matters
A policy of quarantine or reject tells receiving services to move suspicious mail to spam or refuse it. A monitoring-only policy (p=none) records the problem but does not ask receivers to stop spoofed mail.
What to do
After every legitimate sender passes DMARC, move gradually to quarantine and then reject, covering 100% of messages.
Potentially sensitive subdomainsCyStack confirmed at least 212 active DNS subdomains of siteimprove.com. 46 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 @siteimprove.com email addresses appeared in exposed data or information-stealer (infostealer) logs?
There are currently 8 exposed email records matching the siteimprove.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.siteimprove.com expose?
The assessment observed 4 public IPs and 8 open ports for www.siteimprove.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 siteimprove.com have been discovered?
The assessment observed 212+ public subdomains of siteimprove.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.
