This vendor risk report is based on UpGuard's continuous monitoring of access-substrates'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.
When secure cookies are not used, there is an increased risk of third parties intercepting information contained in these cookies. The website configuration should be changed so that all 'Set-Cookie' headers include 'secure'.
No valid Content Security Policy is implemented. This increases the risk of XSS and clickjacking 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.
Browsers may interpret files as a different MIME type than what is specified in the Content-Type HTTP header. This can lead to MIME confusion attacks.
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.
Browsers are prevented from displaying this website's content in frames. This helps mitigate clickjacking attacks.
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 page appears to be maintained.
DMARC policy was not found. This makes it easier for attackers to send email from this domain. A DMARC policy should be deployed for this domain.
Sender Policy Framework (SPF) records prevent spammers from sending messages with forged addresses.
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.
Sender Policy Framework (SPF) record does not include the ptr mechanism.
The 'FTP' service is running and exposed to the internet. The configuration of the server should be reviewed and unnecessary ports closed.
DNSSEC records prevent third parties from forging the records that guarantee a domain's identity. DNSSEC should be configured for this domain.
Domain is not protected from unsolicited deletion requests with the registrar or registry. The domain should have clientDeleteProhibited or serverDeleteProhibited set.
Domain is not protected from unsolicited update requests with the registrar or registry. The domain should have clientUpdateProhibited or serverUpdateProhibited set.
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.
Domain has not expired.
No dangling DNS records that could lead to subdomain takeover were detected.
Domain does not expire within 30 days.
Domain is not flagged as inactive.
Domain is not pending deletion with the registrar.
Domain is not pending restoration with the registrar.
Domain is protected from unsolicited transfer requests.
Domain is not under a DNS resolution hold with the registrar.
Domain is not under a DNS resolution hold with the registry itself.
Domain is not prohibited from renewal at the registry itself.
The domain is still accessible over HTTP. All HTTP requests should be redirected to HTTPS.
The certificate presented by this domain was not issued by a trusted certificate authority and therefore cannot be verified by browsers.
Certificates issued on or after September 1, 2020 must not have a validity period greater than 398 days. The certificate will need to be reissued with a maximum validity of 397 days.
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.
The site's hostname matches the SSL certificate.
SSL certificate has not expired.
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.
SSL certificate does not expire in less than 20% of its total valid period.
Industry standard SHA-256 encryption in use.
The site's public certificate provides at least 112 bits of security strength.
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 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.
