Updated at The higher the score, the more externally observable protections the system has recorded. This page does not certify that the website is reputable, legitimate, or completely free of vulnerabilities.
As of August 26, 2026 at 06:44, jumpjump.io has a security score of 77.7/100 (grade C – “Fair”). CyStack’s automated assessment recorded 14 issues to review after completing 94.6% of applicable checks. The website owner should address “Allowed browser content (CSP)” first, then review the remaining items in order of impact.
At assessment time, CyStack did not find jumpjump.io 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.

Frequently asked questions
A valid SSL certificate still does not prove that jumpjump.io 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.
jumpjump.io used a valid SSL certificate at assessment time, valid until September 26, 2026. This status may change when the certificate expires or the server configuration changes.
Review HTTPS and certificateData sources
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.
CyStack VulnScan continuously discovers assets, validates vulnerabilities, and helps security teams prioritize remediation across the enterprise.
These 3 failed checks or warnings have the greatest impact on the result for jumpjump.io.
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.

References
Why it matters
TLS 1.0 and TLS 1.1 use outdated security designs and are no longer accepted by modern standards. Leaving them enabled allows older, weaker connection methods.
What to do
Disable TLS 1.0 and TLS 1.1, support TLS 1.2 securely, and enable TLS 1.3 where possible.
Evidence and check scope
Why it matters
Cross-Origin Resource Sharing (CORS) decides which websites may read responses from this service in a visitor's browser. Rules that trust arbitrary origins, especially with login cookies, can expose private data to another website.
What to do
Allow only explicitly trusted websites, compare the Origin value with an exact approved list, and never allow login credentials with the wildcard origin (*).
Each public IP is grouped with its open services, identified products and any CVEs that may apply to the observed version.

Review exposed email recordsThe assessment identified 33 technologies on jumpjump.io, but no version was reliable enough for accurate CVE matching.
Review technologies and CVEsThe assessment observed 2 public IPs and 8 open ports for jumpjump.io. An open port is not the same as a vulnerability, but the website owner should keep every public service updated and appropriately restrict access.
Review IPs and open portsThe assessment observed 7+ public subdomains of jumpjump.io. 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.
