As a result, the operational problems related to using USB tokens or by storing private keys locally are eliminated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, KeyLocker allows developers to sign their code remotely from any location using protected keys within DigiCert&#8217;s secure infrastructure. This solution is typically provisioned when ordering a code signing certificate from DigiCert CertCentral, making it easy to deploy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Read More on: <\/strong><a href=\"https:\/\/signmycode.com\/blog\/what-is-digicert-keylocker-everything-to-know-about\">KeyLocker Benefits, Working, Integration<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-digicert-software-trust-manager\">What Is DigiCert\u00ae Software Trust Manager?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/signmycode.com\/digicert-software-trust-manager\">DigiCert Software Trust Manager<\/a> is a holistic software supply chain security framework, going beyond just securely storing keys.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Software Trust Manager uses the same\u00a0<a href=\"https:\/\/signmycode.com\/blog\/what-is-a-cloud-hardware-security-module-right-cloud-hsm-for-code-signing\">cloud-based HSM<\/a>\u00a0technology that protects code signing keys; however, it also includes governance, policy enforcement, threat scanning, and compliance management, making this product perfect for companies that require more than just secure keys.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Additionally, Software Trust Manager can be integrated into a <a href=\"https:\/\/signmycode.com\/blog\/what-is-ci-cd-detailed-guide-on-ci-cd-pipeline\">CI\/CD (Continuous Integration \/ Continuous Deployment) pipeline<\/a> to automate scanning and signing processes. This will also allow for role-based access control, an approval process, an audit log of activities, the generation of <a href=\"https:\/\/signmycode.com\/blog\/what-is-a-software-bill-of-material-sbom-and-supply-chain-security\">Software Bills of Material (SBOM)<\/a>, and signing enforcement driven by policy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As such, it provides value to organizations that are responsible for managing a complex development workforce, accommodating regulatory compliance, and interacting with changing cryptographic standards, such as future preparation for <a href=\"https:\/\/signmycode.com\/blog\/pqc-code-signing-in-a-cnsa-2-0-world-preparing-for-the-quantum-leap\">post-quantum cryptography<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Read More on<\/strong> <a href=\"https:\/\/signmycode.com\/blog\/what-is-digicert-software-trust-manager\">Software Trust Manager Features, Tools, and Integration <\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-software-trust-manager-vs-digicert-keylocker-difference\">Software Trust Manager vs DigiCert KeyLocker Difference<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td><strong>Feature<\/strong><\/td><td><strong>DigiCert KeyLocker<\/strong><\/td><td><strong>DigiCert Software Trust Manager<\/strong><\/td><\/tr><tr><td><strong>Cloud HSM Storage<\/strong><\/td><td>Yes<\/td><td>Yes<\/td><\/tr><tr><td><strong>FIPS Compliance<\/strong><\/td><td>Yes (Level 3)<\/td><td>Yes (Cloud HSM compliant)<\/td><\/tr><tr><td><strong>Role-Based Access Control (RBAC)<\/strong><\/td><td>Limited<\/td><td>Advanced team-based RBAC<\/td><\/tr><tr><td><strong>Multiple Simultaneous Signers<\/strong><\/td><td>Not Designed For<\/td><td>Supported<\/td><\/tr><tr><td><strong>Threat Scanning<\/strong><\/td><td>No<\/td><td>Yes<\/td><\/tr><tr><td><strong>SBOM Generation &amp; Signing<\/strong><\/td><td>No<\/td><td>Yes<\/td><\/tr><tr><td><strong>Policy-Driven Signing<\/strong><\/td><td>No<\/td><td>Yes<\/td><\/tr><tr><td><strong>CI\/CD Integration<\/strong><\/td><td>Basic Signing<\/td><td>Deep DevOps Integration<\/td><\/tr><tr><td><strong>Audit Logs<\/strong><\/td><td>Basic<\/td><td>Detailed &amp; Auditable<\/td><\/tr><tr><td><strong>PQC-Ready Encryption<\/strong><\/td><td>Not Core Focus<\/td><td>Supported<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-when-to-choose-digicert-keylocker\">When to Choose DigiCert KeyLocker<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-if-you-only-need-secure-compliant-key-storage\">If You Only Need Secure, Compliant Key Storage<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If your organization\u2019s primary concern is protecting private keys used for code signing then KeyLocker is a viable option.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">KeyLocker allows you to create and store your private keys within a FIPS 140-2 Level 3 compliant cloud HSM (hardware security module) environment, thus significantly decreasing the potential for key compromise.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">By using DigiCert KeyLocker, you do not have to invest in an expensive <a href=\"https:\/\/signmycode.com\/blog\/cloud-hsm-vs-on-premises-hsms-choosing-the-right-encryption-solution\">on-premise HSM infrastructure<\/a>; you can use cloud-based storage options that are compliant with industry standards and keep your management overhead low.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Recommended:<\/strong> <a href=\"https:\/\/signmycode.com\/resources\/how-to-purchase-a-digicert-keylocker-certificate\">How to Purchase a DigiCert\u200b\u200b\u200b\u200b KeyLocker Certificate?<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-if-you-want-to-eliminate-hardware-tokens\">If You Want to Eliminate Hardware Tokens<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Many organizations still use <a href=\"https:\/\/signmycode.com\/blog\/code-signing-with-usb-tokens-a-comprehensive-guide\">USB tokens to securely store their code signing keys<\/a>. While this may be a viable option, it can lead to operational bottlenecks and security risks (e.g., tokens can become lost, stolen, damaged, or locked onto one physical machine).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With KeyLocker, you can eliminate these risks by transferring your private key storage from token-based systems to cloud-based storage. As a result, authorized individuals can now sign code from anywhere with internet access, rather than relying on a token.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In addition, once you have moved to KeyLocker, you will have less need to worry about access restrictions when managing your key protection processes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-if-your-signing-workflow-is-simple-and-centralized\">If Your Signing Workflow Is Simple and Centralized<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">For teams that have basic signing procedures and are relatively small to mid-sized, there really is no need to have advanced features for governance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In these cases, if you only have a handful of signers and do not require complex approval processes or policies to govern how each member should act as a signer, then KeyLocker offers a fantastic solution that is uncomplicated.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is to operate and gives you the ability to securely sign without adding any complexity to your day-to-day operations.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Recommended:<\/strong> <a href=\"https:\/\/signmycode.com\/resources\/how-to-configure-digicert-keylocker-on-windows\">How to Configure DigiCert KeyLocker on Windows?<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-if-you-don-t-require-built-in-threat-scanning-or-sbom-management\">If You Don\u2019t Require Built-In Threat Scanning or SBOM Management<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">KeyLocker fits best in an environment where a company manages its own vulnerability scanning and compliance checks through third-party tools or processes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It has no built-in scanning of malware or creation of SBOMs (Software Bill Of Materials) and does not have any sort of policy enforcement capabilities; thus, organizations can manage their own data through other third-party tools and processes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Therefore, KeyLocker provides an effective method for securely storing and providing access to the keys it creates, but it has no overlapping features.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Recommended:<\/strong> <a href=\"https:\/\/signmycode.com\/resources\/troubleshooting-most-common-sbom-signing-errors\">Most Common SBOM Signing Errors<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-when-to-choose-digicert-software-trust-manager\">When to Choose DigiCert Software Trust Manager<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-if-you-need-enterprise-level-governance-and-control\">If You Need Enterprise-Level Governance and Control<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Software Trust Manager is meant for organizations requiring governance of their entire code signing ecosystem.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Whether you have one department with multiple teams or have a centralized code signing organization with multiple teams spanning multiple locations, you would utilize Software Trust Manager\u2019s role-based access control (RBAC), activity log, and policy enforcement features.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Properly managing signatures will align with your defined security policies, with all actions being traceable for compliance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Recommended:<\/strong> <a href=\"https:\/\/signmycode.com\/blog\/nist-supply-chain-security-guidance-for-ci-cd-environments\">NIST Supply Chain Security Guidance for CI\/CD Environments<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-if-you-want-integrated-threat-scanning-before-signing\">If You Want Integrated Threat Scanning Before Signing<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In the current software supply chain, if code is signed that is either vulnerable to attack or infected with a virus, it can cause significant reputational or financial harm.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Software Trust Manager integrates virus detection, vulnerability scanning, CVE verification against known vulnerabilities, and license validations as an integral part of the signing workflow to ensure that your entire code signing process has been fully evaluated prior to being signed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As such, you minimize the probability of releasing compromised software that does not comply with your organization\u2019s defined security policies.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-policy-based-signing-and-approvals-workflows-required\">Policy-Based Signing and Approvals Workflows Required<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Strict approval workflows are common in the regulated industry for software releases.
