Fractional IT for fast-growing companies
Service we Offer
As a founder or early employee at a startup, you’re likely juggling countless priorities with limited time and resources. Security often falls to the bottom of the list—until there’s a problem. I’ve spent years working with startups and have seen firsthand how devastating security incidents can be for early-stage companies. Recent data shows that 43% of cyberattacks specifically target small businesses, yet many founders still believe they’re “too small to be targeted.” This dangerous misconception leaves many startups vulnerable.
Network Right has helped hundreds of venture-backed startups, from pre-seed through Series E, build security programs that pass enterprise customer reviews and SOC 2 audits. We operate from San Francisco and New York with partnerships across Okta, Vanta, Drata, and Cisco.
Startups get breached because attackers know they store valuable data and lack the resources to defend it. Verizon's 2024 Data Breach Investigations Report found that 46% of cyber breaches hit companies with fewer than 1,000 employees. The average cost of a breach for a small business ranges from $120,000 to $1.24 million, and 60% of small businesses that experience a significant cyberattack close within six months.
The good news: you do not need an enterprise budget to build real security. You need the right controls at the right stage, applied in the right order. This guide maps cybersecurity to your startup's funding stage, gives you specific cost ranges, and covers the SaaS-specific protections that most guides miss.
Network Right specializes in building security programs for startups and growth-stage technology companies. We assign a dedicated security expert to your team who handles everything from initial cloud configuration hardening through SOC 2 audit preparation, so you can focus on building your product and closing customers.
Attackers target startups for three reasons: startups hold valuable intellectual property and customer data, they typically have immature security controls, and they lack dedicated security staff to detect and respond to incidents.
Common attack vectors include phishing emails targeting founders and early employees, exploitation of unpatched software and default cloud configurations, weak or shared passwords across critical systems, insecure API endpoints and third-party integrations, and supply chain attacks through SaaS vendors.
The misconception that "we're too small to be a target" is the most dangerous belief a founder can hold. Automated attack tools scan the entire internet indiscriminately. They don't check your headcount before attempting to exploit a misconfigured S3 bucket or brute-force a login page without MFA.
Your cloud provider also does not handle security for you. AWS, Azure, and GCP all operate under a shared responsibility model: they secure the infrastructure, but your applications, data, access controls, and configurations are your responsibility. A fractional IT partnership that scales with your team can close the gap between what your cloud provider covers and what your startup actually needs protected.
The biggest mistake startups make with security is trying to implement everything at once. Security should match your company's stage, team size, risk profile, and customer requirements. Here is what to prioritize at each stage.
At this stage, you need protection against the most common attack vectors with near-zero budget. Focus on four things:
Multi-factor authentication everywhere. MFA prevents 99.9% of account compromise attacks according to Microsoft. Enable it on every account, especially email, cloud consoles, code repositories, and financial systems. Use an authenticator app (not SMS) for the second factor. Hardware security keys ($25-50 each) are worth it for founder and root admin accounts.
A company-wide password manager. Poor password practices are implicated in over 80% of breaches. Deploy Bitwarden (free tier) or 1Password for Teams ($3-7/user/month). Require unique passwords for every account and eliminate credential sharing over Slack or email.
Cloud configuration hardening. Review IAM permissions, enable logging, restrict public access to storage buckets, and separate development from production environments. Use your cloud provider's free security tools: AWS Security Hub, Google Security Command Center, or Azure Security Center.
Basic backup procedures. Follow the 3-2-1 rule: three copies of critical data, on two different media types, with one copy off-site. Cloud backup services run $5-20/month for early-stage needs.
A dedicated service desk that resolves issues fast can also help pre-seed teams handle day-to-day IT without pulling engineering time away from product work.
With initial capital and a growing team, formalize the practices you started and add vulnerability scanning to your development workflow.
Security policies. Write three documents: acceptable use policy, data handling policy, and incident response plan. Keep each under two pages. SANS offers free templates you can adapt.
Security awareness training. Phishing is the top attack vector for startups. Run quarterly phishing simulations and security awareness training to build recognition skills across your team. Free tools like Gophish work for basic simulations, but professional programs provide more sophisticated campaigns tailored to your industry.
Development security integration. Add automated security scanning to your CI/CD pipeline. OWASP ZAP (free) for web application scanning, Snyk (free tier) for dependency vulnerabilities, and GitHub Advanced Security for code scanning. Dedicate 5% of engineering time to security tasks.
Data classification. Label your data into four tiers: public, internal, confidential, and restricted. Define who can access each tier and how each tier should be encrypted, stored, and eventually deleted. This classification becomes the foundation for compliance work later.
Start working with IT services built for startup speed at this stage if you don't have internal IT. The cost of a security incident at Seed stage, when you're building your first enterprise pipeline, can set you back quarters.
Total estimated cost at this stage: $2,000-3,000/month for a team of 25.
Series A is where security shifts from "good hygiene" to "business requirement." Enterprise customers start asking for SOC 2 reports, and investors expect a formal security posture during due diligence.
Hire security leadership (fractional or full-time). Most startups at this stage can't justify a $250,000-350,000 full-time CISO salary. A virtual CISO provides strategic security leadership at $2,000-5,000/month: risk assessments, security roadmaps, vendor security questionnaire responses, and board-level reporting. Our full guide to vCISO services explains when fractional security leadership makes sense versus a full-time hire.
Start SOC 2 readiness. If you sell B2B SaaS to mid-market or enterprise customers, SOC 2 is not optional. It's the table stakes certification buyers expect. Start with a readiness assessment ($5,000-10,000) to identify your gaps, then implement controls incrementally. Budget $20,000-50,000 for your first SOC 2 Type 2 certification. We cover the full SOC 2 readiness process, including the five Trust Service Criteria, Type 1 vs. Type 2 differences, and a compliance checklist, in our SOC 2 compliance guide.
External penetration testing. Hire a third party to test your application and infrastructure at least annually. Comprehensive pen tests run $10,000-25,000. Web application-only tests start around $5,000-10,000.
Endpoint detection and response (EDR). Deploy EDR across all company devices. Solutions like CrowdStrike, SentinelOne, or Microsoft Defender for Endpoint run $5-15/endpoint/month. This is your first line of defense against malware and lateral movement.
Build strong documentation and strategic planning practices at this stage. Every security control you implement should be documented with clear ownership, review cadence, and evidence collection procedures. This documentation pays dividends during SOC 2 audits and enterprise security reviews.
Total estimated cost at this stage: $5,000-15,000/month for a team of 50.
At this stage, you need a mature security program with 24/7 monitoring, formal compliance certifications, and security embedded into every business function.
Managed SOC or 24/7 monitoring. Your security team (even a good one) can't monitor alerts around the clock. A managed security operations center provides 24/7 threat detection and response at $15-50/endpoint/month, significantly less than building an in-house SOC (which requires a minimum of 5-6 FTEs at $100,000-150,000 each). Our managed SOC page details what's included: staffing model, technology stack, response times, and escalation procedures.
Cloud security posture management. As your cloud footprint grows across AWS, Azure, and GCP, misconfigurations multiply. CSPM tools continuously scan for security gaps, compliance violations, and overly permissive access. Network Right's managed cloud security services handle cloud workload protection, container security, and multi-cloud compliance monitoring for growth-stage companies.
Zero trust architecture. Move beyond perimeter-based security. Implement identity-aware access policies using tools like Okta for identity and Twingate for zero-trust network access. Verify every user, device, and connection before granting access to any resource.
Formal compliance certifications. Pursue SOC 2 Type 2 (annual audit), and add ISO 27001 or GDPR compliance if your customers or industry require it. Automated compliance platforms like Vanta or Drata ($10,000-25,000/year) reduce the documentation burden.
Total estimated cost at this stage: $15,000-50,000+/month depending on team size and compliance requirements.
The standard guidance is 3-5% of your IT budget for early-stage companies, increasing to 7-10% as you scale or enter regulated industries. But percentages aren't helpful without context. Here are specific budget ranges by company size:
10-person fintech startup (Pre-seed). You handle sensitive financial data from day one. Budget $400/month: $70 for 1Password team plan, $200 for cloud security tooling, $100 for backup services, and $30 for a VPN. Spend a weekend hardening your AWS configuration using CIS benchmarks. This baseline prevents the vast majority of automated attacks.
50-person SaaS company (Series A). Your first enterprise prospect just asked for your SOC 2 report. Budget $10,000/month: $3,500 for a vCISO retainer (Network Right handles this), $2,000 for SOC 2 readiness and compliance tooling, $1,500 for EDR across all endpoints, $1,500 for security training and phishing simulations, and $1,500 for cloud security monitoring. Amortize your pen testing cost ($15,000 annually) at about $1,250/month.
100-person healthtech company (Series B). You need HIPAA compliance, SOC 2 Type 2, and 24/7 monitoring for sensitive patient data. Budget $30,000/month: $5,000 for managed SOC services, $5,000 for a vCISO, $8,000 for compliance management (SOC 2 + HIPAA), $4,000 for EDR and CSPM, $3,000 for security training across the full team, and $5,000 for incident response retainer and pen testing. Check out managed IT services from providers who know startups to compare options for bundling these services.
Outsource when the function requires specialized expertise you'll use periodically (penetration testing, incident response), when you need 24/7 coverage (security monitoring), or when you need strategic leadership without full-time cost (vCISO services).
Keep in-house when the function is core to your product (application security for a security company), when daily operational context is required (security champion within the dev team), or when you've scaled past 300 employees and can justify a dedicated 3-5 person security team.
Most startups between 25 and 200 employees get the best results with a hybrid model: a fractional or full-time security lead who coordinates outsourced services for monitoring, compliance, testing, and incident response.
SaaS startups face security challenges that physical-product or services companies don't. If your product runs in the cloud and serves multiple customers from shared infrastructure, these sections are for you.
Multi-tenant architecture means a vulnerability in one customer's environment can potentially affect all customers. Key controls include strict tenant isolation at the data layer (separate databases or robust row-level security), per-tenant encryption keys, and access controls that prevent horizontal privilege escalation between tenants.
Test tenant isolation regularly. A pen test should specifically attempt to access one tenant's data from another tenant's session. If your pen tester can do it, so can an attacker.
APIs are the most common attack surface for SaaS companies. Protect them with authentication on every endpoint (OAuth 2.0 or API keys at minimum), rate limiting to prevent abuse and brute-force attacks, input validation on all parameters, and audit logging for every API call that touches sensitive data.
Use OWASP's API Security Top 10 as your checklist. The most common SaaS breaches in 2024-2025 exploited broken object-level authorization (BOLA), where an API returns data for any customer ID without verifying the requester has access to that specific customer's data.
When you sell internationally, data residency becomes a compliance requirement. Map your data flows: where customer data is collected, processed, stored, and backed up. Build mechanisms for data access requests, correction, and deletion to comply with GDPR, CCPA, and emerging state privacy laws.
For remote IT support that keeps distributed teams secure, you need consistent security policies that apply regardless of where your team members or customers are located.
Consider geographic data residency requirements early. Retrofitting data location controls into a mature application is expensive and disruptive. Most cloud providers offer region-specific data storage, but your application layer needs to enforce it too.
Tools and policies only work if your team uses them. Security culture means every employee understands that security is part of their job, not just IT's job.
Skip the annual 45-minute compliance video. Instead, run short monthly sessions (15-20 minutes) focused on one topic: phishing recognition this month, secure code review next month, data handling the month after. Rotate a "security champion" role among engineers each quarter to spread awareness across the development team.
Pair training with network monitoring and management for growing teams to catch the threats that slip past training. People will make mistakes. Your monitoring should catch what training misses.
Sales teams need to understand your security posture well enough to answer customer security questionnaires accurately. Prepare a standard security documentation package they can share during the sales process. Marketing needs to make accurate security claims. Customer support must verify user identity before providing account access and recognize potential security incidents in customer reports. Finance must implement secure payment processing and protect sensitive employee and vendor data.
Create a security page on your website that covers your certifications, compliance status, security practices, and data handling policies. Prepare a downloadable security overview document for sales teams. For investors, include security milestones in your business plan and quantify security investments as risk reduction, not just cost.
Companies that demonstrate compliance support including SOC 2 and HIPAA readiness close enterprise deals faster. Compliance reduces sales cycle friction from weeks to days once you have your documentation in order.
Every startup needs an incident response plan before an incident happens. The plan should cover:
Detection and classification. Who monitors for security events? What classifies as an incident versus a false positive? Define severity levels (critical: active data breach, high: compromised account, medium: phishing attempt detected, low: policy violation).
Response team and responsibilities. Name specific people: who leads the response, who handles technical containment, who manages customer communication, who notifies legal. For startups without dedicated security, this is often the CTO or a senior engineer, the CEO for communications, and outside counsel.
Containment procedures. Step-by-step instructions for isolating compromised systems, resetting credentials, revoking API keys, and preserving forensic evidence. Practice these steps before you need them.
Communication templates. Pre-written templates for customer notification, employee notification, regulatory notification, and public statements. Writing these under pressure during an active breach leads to poor communication.
Post-incident review. Every incident gets a blameless retrospective within one week. Document what happened, how it was detected, how it was contained, and what changes will prevent recurrence.
Test your plan with a tabletop exercise at least annually. Walk through a realistic scenario (a phishing attack compromises an admin account, ransomware encrypts your production database) and identify where the plan breaks down.

What is the minimum viable security program for a pre-seed startup? Deploy multi-factor authentication on every account, use a company-wide password manager, harden your cloud configuration using provider best practices, set up automated backups, and write a basic incident response plan. This foundation costs under $500/month for a team of 10 and protects against the most common attack vectors targeting early-stage companies.
When should a startup hire its first security person? Most startups don't need a dedicated security hire until they reach 50-75 employees or begin enterprise sales that require SOC 2 certification. Before that point, a virtual CISO ($2,000-5,000/month) provides strategic security leadership without the cost of a full-time executive. Your first full-time security hire typically makes sense around Series B.
How much should a startup budget for cybersecurity? Pre-seed startups with 10 employees should budget $200-500/month. Seed-stage companies with 25 employees need $1,000-3,000/month. Series A companies with 50 employees should plan for $5,000-15,000/month. At Series B with 100+ employees, expect $15,000-35,000/month. The standard rule of thumb is 3-5% of IT budget at early stage, rising to 7-10% as you scale.
What is the most cost-effective security investment for a startup? Multi-factor authentication. It prevents 99.9% of account compromise attacks, costs nothing to enable on most platforms, takes hours to deploy across a company, and addresses the single most common attack vector. After MFA, prioritize a password manager and cloud configuration hardening.
When does a startup need SOC 2 certification? When your first enterprise customer or mid-market prospect asks for it, which typically happens around Series A or when your annual deal sizes exceed $50,000. Start SOC 2 readiness 6-9 months before you expect to need the certification. A readiness assessment costs $5,000-10,000, and first-time SOC 2 Type 1 certification runs $20,000-50,000 depending on complexity.
How do you balance security with rapid development speed? Integrate security into your existing development workflow rather than adding a separate gate. Automated security scanning in your CI/CD pipeline catches vulnerabilities without slowing releases. Create reusable secure components (authentication modules, input validation libraries, encrypted storage helpers) that developers use by default. Dedicate 5% of engineering sprints to security tasks.
