This vendor risk report is based on UpGuard's continuous monitoring of Sunrise's security posture using open-source, commercial, and proprietary threat intelligence feeds. The results are summarized into a security rating based on the analysis of hundreds of individual checks across five risk categories: website security, email security, phishing & malware, brand & reputation risk, and network security.
The Content Security Policy may not restrict sources appropriately, or may contain 'unsafe-inline' without the use of a nonce or hash. This increases the risk of XSS attacks.
When HttpOnly cookies are not used, the cookies can be accessed on the client, which enables certain type of client-side attacks. The website configuration should be changed to enforce HttpOnly cookies.
Using secure cookies reduces the risk of third parties intercepting information contained in these cookies.
Ensuring the server information header is not exposed reduces the ability of attackers to exploit certain vulnerabilities.
Information about specific technology used on the server is obscured.
The Content Security Policy does not allow any insecure active sources.
The website's Referrer Policy is not configured to allow unsafe information to be sent in the referrer header.
Ensuring the ASP.NET version header is not exposing a specific version makes it harder for attackers to exploit certain vulnerabilities.
Ensuring the ASP.NET version header is not exposed makes it harder for attackers to exploit certain vulnerabilities.
The Content Security Policy does not allow any insecure passive (img/media) sources.
A Content Security Policy is implemented to help protect against XSS and clickjacking attacks.
Browsers are prevented from interpreting files as a different MIME type to what is specified in the Content-Type HTTP header. This helps mitigate MIME confusion attacks.
The page appears to be maintained.
The DMARC policy should be set to p=reject for maximum protection.
DMARC protects against fraudulent emails being sent from a domain.
Sender Policy Framework (SPF) record strictly enforces specific domains allowed to send email on its behalf.
Sender Policy Framework (SPF) record passes basic syntax checks.
DMARC policy percentage is set to default 100%, ensuring all mail is covered by the policy.
Sender Policy Framework (SPF) record does not include the ptr mechanism.
DNSSEC records prevent third parties from forging the records that guarantee a domain's identity. DNSSEC should be configured for this domain.
The domain does not contain a valid Certification Authority Authorization (CAA) record. A CAA record indicates which Certificate Authorities (CAs) are authorized to issue certificates for a domain.
No unregistered MX records that could lead to receiving mail on behalf of the target organization were detected.
No dangling DNS records that could lead to subdomain takeover were detected.
The domain was not found on the HSTS preload list. Users who visit the website for the first time will be vulnerable to MITM attacks. The requirements for inclusion on the preload list are specified by hstspreload.org.
The HTTP Strict Transport Security (HSTS) header does not contain the includeSubDomains directive. This directive instructs the browser to also enforce the HSTS policy over subdomains of this domain.
Weak cipher suites can potentially be broken by a well resourced attacker, and should not be supported by the server unless very old devices or browsers must be supported.
The site's certificate chain was checked against our list of revoked certificates.
SSL is supported for this site.
All HTTP requests are redirected to HTTPS.
The site's hostname matches the SSL certificate.
SSL certificate has not expired.
The certificate presented by this domain was issued by a trusted certificate authority.
With HSTS enforced, people browsing this site are less susceptible to man-in-the-middle attacks.
No insecure SSL/TLS versions are available for this site.
A complete SSL certificate chain was presented by the server for this domain.
SSL intermediate and root certificates do not expire within 20 days.
The SSL certificate presented by the server has an expiration period shorter than 398 days.
SSL certificate does not expire in less than 20% of its total valid period.
Industry standard SHA-256 encryption in use.
TLS connections to the site use a strong Diffie-Hellman prime during key exchange.
The site's public certificate provides at least 112 bits of security strength.
Our scans have not found any evidence of infostealer malware infections associated with this organisation's domain.
No cloud storage service configured to allow anonymous file listing was detected.
The domain index is not a listable directory.
This website does not appear to contain malicious code.
This IP/domain has not been reported as a source of botnet activity in the last 30 days.
This IP/domain did not appear on any list of IPs and domains known to perform brute force login attempts in the last 30 days.
This IP/domain has been reported for distributing malware in the last 30 days.
This IP/domain has not been reported for performing unsolicited scanning in the last 30 days.
This website does not appear to be attempting to install unwanted software.
This site does not appear to be a forgery or imitation of another website.
This IP/domain has not been reported as a phishing site in the last 30 days.
This IP/domain has not been reported as a source of botnet activity in the last 90 days.
This IP/domain did not appear on any list of IPs and domains known to perform brute force login attempts in the last 90 days.
This IP/domain has been reported for distributing malware in the last 90 days.
This IP/domain has not been reported for performing unsolicited scanning in the last 90 days.
This IP/domain has not been reported as a phishing site in the last 90 days.
A bug in OpenSSL's implementation of the TLS heartbeat extension allows access to portions of memory on the targeted host e.g. cryptographic keys and passwords.
The server does not support SSLv3, and is not vulnerable to the POODLE attack.
The server does not offer RSA_EXPORT cipher suites, so clients are not vulnerable to the FREAK attack.
The server is using strong Diffie-Hellman parameters and is not vulnerable to the Logjam attack.
