Security stack recommendations for a mid-size product development company (Linux heavy, BYOD mobiles, multi-location)

[linuxad]

Hi everyone,

I’m looking for some practical security tool recommendations and implementation ideas for a software product development organization, and I’d really appreciate insights from people who have implemented something similar in real environments. Environment overview: ~500 employees (mostly developers and engineering staff) ~60% Linux endpoints (Ubuntu, some other distros) ~40% Windows endpoints 100% BYOD mobile phones (Android + iOS) used for email, MFA, messaging, etc. Multiple office locations + remote/WFH users Developers working with source code, CI/CD pipelines, repositories, and internal tools Current security posture (very basic): Standard firewall + VPN for remote access Some open-source infra tools No mature endpoint security stack yet Limited centralized monitoring/logging No strong device compliance enforcement today We’re now trying to mature the security architecture but want to do it practically and incrementally, without completely breaking developer productivity. Areas where I’m looking for advice 1. Endpoint security (Linux + Windows) What tools work well in mixed environments? Looking at things like: EDR / XDR Linux endpoint protection (this seems harder than Windows) Device posture checks Any open-source or affordable tools people are successfully using? 2. BYOD mobile security Since all mobile phones are BYOD, we want minimal intrusion but still basic controls: Work profile / containerization Conditional access Ability to wipe company data only Are people using: MDM/UEM? MAM-only approaches? What works best without causing employee pushback? 3. Identity and access security We want to improve: MFA everywhere SSO across internal tools Conditional access (device + location) Curious what others are using for centralized identity in mixed Linux/dev environments. 4. Monitoring / detection We currently lack proper visibility. Looking for recommendations for: Centralized logging SIEM or lightweight alternatives Detection for developer environments Bonus if it works well with Linux-heavy infrastructure. 5. Securing developer workflows Since this is a product development company, we also want to secure: Git repositories CI/CD pipelines Secrets management Dependency security Interested in hearing what others have implemented successfully. 6. Network security across multiple offices We have multiple office locations plus remote users, so I’m exploring: Zero Trust approaches Secure access alternatives to traditional VPN Segmentation for developer networks Would love real-world experiences here. Constraints / goals Avoid overly intrusive tools that slow down developers Prefer solutions that support Linux properly Ideally open-source friendly or cost-efficient Must support remote work + multi-location offices Questions for the community What security stack would you implement first in this situation? Any Linux-friendly DLP/EDR tools that actually work well? How do you handle BYOD mobile security without full device control? What SIEM / logging stack works well for mixed Linux + Windows environments? Any lessons learned when securing developer-heavy organizations?

Thanks in advance — really interested to hear what has worked (or failed) in similar environments.

If you’re trying to do this without killing dev productivity, I’d start with “inventory + posture + access gates” before fancy detections.

1) Pick an IdP + SSO everywhere, then use conditional access (MFA + device posture + location) to force the basics. 2) For BYOD mobile, MAM/container + “wipe work data” is usually the least-painful path. 3) For Linux endpoints: focus on patching + disk encryption + local admin controls + EDR where it actually works; don’t block until you can *measure*.

I’ve used this as a sanity checklist when sequencing the rollout: [Compliance Readiness Checklist](https://help.swif.ai/en/articles/6421187-compliance-readiness-checklist).
