Room For Improvement

CAST Highlight needs detailed reports, improved dashboards, customization, better support, and OS-specific blockers amid high costs and sharing issues.
Snyk users seek enhanced language support, plugin integration, vulnerability visibility, and improvements in UI, reporting, and training features.
Understanding only the OS-specific blockers means I would avoid resolving irrelevant issues, thus saving time.
Technical Associate Manager at Accenture
CAST Highlight's deduplication is great for avoiding spam, but sometimes we want two similar quotes if they are from very different company sizes, such as SMB versus enterprise perspectives on pricing.
Senior Data Engineer at LTM
It lacks the ability to select branches on its Web UI, forcing users to rely on CLI or CI/CD for that functionality.
CEO at a computer software company with 10,001+ employees
The inclusion of AI to remove false positives would be beneficial.
Director at Marsh
As we are moving toward GenAI, we expect Snyk to leverage AI features to improve code scanning findings.

Setup Cost

CAST Highlight is seen as costly due to per-scan fees, despite being cheaper than CAST AIP.
Snyk provides valuable, flexible pricing and robust features for enterprises, often considered affordable compared to Veracode and Black Duck.
Snyk is recognized as the cheapest option we have evaluated.
CEO at a computer software company with 10,001+ employees
After negotiations, we received a special package with a good price point.

Snyk enhances security with AI-powered vulnerability scanning, seamless integration, and efficient management across various tools and programming languages.
Smart deduplication groups similar quotes and picks the strongest and most significant one. It stops insights from showing eight variations of great UI, giving diverse voices instead of repetition.
Senior Data Engineer at LTM
In cloud migration, I use CAST highlight to identify blockers, which are the negative road patterns, and also the boosters, which are positive code patterns.
Technical Associate Manager at Accenture
Our integration of Snyk into GitHub allows us to automatically scan codebases and identify issues, which has improved efficiency.
CEO at a computer software company with 10,001+ employees
Snyk helps detect vulnerabilities before code moves to production, allowing for integration with DevOps and providing a shift-left advantage by identifying and fixing bugs before deployment.
Director at Marsh

Featured Reviews

Nishant Chauhan - PeerSpot reviewer
Senior Data Engineer at LTM
Automated code insights have improved security checks and made review workflows more consistent
If I talk about improvements for CAST Highlight, I would suggest three things. The first is better understanding or niche understanding. Right now, the intent matching is strong for general topics such as ease of use, but for niche B2B terms such as HIPAA compliance or multi-tenant architecture, it sometimes misses context. Improving the domain-specific models would make highlights more accurate for these verticals. The second improvement is more control over the deduplication logic. CAST Highlight's deduplication is great for avoiding spam, but sometimes we want two similar quotes if they are from very different company sizes, such as SMB versus enterprise perspectives on pricing. A slider to adjust deduplication strictness would help. The third suggestion I would like to give is deeper sentiment and outcome tagging. While it has core sentiment capabilities, it does not tag outcomes automatically. For instance, if a quote mentions saved $50,000 per year, tagging that as cost savings $50,000 would let us build ROI charts instantly instead of reading each quote manually. Regarding user experience, integrations, and reporting, I think there is room to enhance those aspects. Regarding user experience, I would suggest improving user actions in terms of bulk actions and keyboard shortcuts. Day-to-day analysts review 50-plus suggested quotes, and currently it is mostly clicking to approve one by one. Adding bulk approve or reject options and keyboard shortcuts would significantly reduce the time taken. A small UX change can lead to a big speed boost. The second point is integrations when pushing to the CMS and Slack alerts. Right now, we export approved highlights manually from CAST Highlight. If CAST Highlight could push directly to our CMS or send Slack alerts for high-strength quotes that hit trending topics, it would close the loop faster, reducing copy-pasting. The third improvement relates to reporting, specifically custom insight dashboards. The tool displays which topics have the most highlights, but we cannot build custom dashboards yet. For example, showing all security quotes from healthcare companies with more than 1,000 employees over the last 90 days would enable better filtering, and exportable dashboards would streamline quarterly reviews.

Improves security posture by actively reducing critical vulnerabilities and guiding remediation
Snyk's main features include open-source vulnerability scanning, code security, container security, infrastructure as code security, risk-based prioritization, development-first integration, continuous monitoring and alerting, automation, and remediation. The best features I appreciate are the vulnerability checking, vulnerability scanning, and code security capabilities, as Snyk scans all open-source dependencies for known vulnerabilities and helps with license compliance for open-source components. Snyk integrates into IDEs, allowing issues to be caught as they appear in the code dynamically and prioritizes risk while providing remediation advice. Snyk provides actionable remediation advice on where vulnerabilities can exist and where code security is compromised, automatically scanning everything and providing timely alerts. Snyk has positively impacted my organization by improving the security posture across all software repositories, resulting in fewer critical vulnerabilities, more confidence in overall product security, and faster security compliance for project clients. Snyk has helped reduce vulnerabilities significantly. Initially, the repository had 17 to 31 critical and high vulnerabilities, but Snyk has helped manage them down to just five vulnerabilities, which are now lower and not high or critical.
